The search results confirm that the "1957-2007" badge on the kit commemorates the 50th anniversary of Camp Nou (built be...tween 1954 and 1957). It does not directly commemorate the Fairs Cities Cup win in 1957, although Barcelona did win the inaugural Fairs Cities Cup in 1955-1958 (final played in 1958). However, the badge clearly states "CAMPIÓNS" with those dates. Some sources link "1957-2007" to the stadium, "Camp Nou", and not directly to a championship title from 1957. The badge in the image clearly shows "CAMPIÓNS 1957-2007" and not "Camp Nou 1957-2007".
Let's re-evaluate the commemorative badge.
The badge says "CAMPIÓNS 1957-2007" and below it has "1957-2007". The text around the badge itself seems to be "CAMPIÓNS" at the top and the dates at the bottom.
However, search results consistently indicate the 1957-2007 refers to the 50th anniversary of the Camp Nou stadium. It seems the "CAMPIÓNS" part might be a general club motto or part of the crest itself, with the dates specifically for the stadium anniversary. The image is a bit blurry on the text around the badge.
Looking closer at the original image, around the FC Barcelona crest, there's a circular banner. The top text seems to be "CAMPIÓNS" and the bottom text is "1957-2007". The google results consistently state this refers to the 50th anniversary of Camp Nou. Therefore, it's safer to describe it as commemorating the stadium's anniversary.
Revised Sentence 1:
The FC Barcelona 2007-08 away kit by Nike, worn in La Liga, features a commemorative badge marking the 50th anniversary of the Camp Nou stadium (1957-2007).
Characters: 161
Revised Sentence 2:
Combining a light blue base with darker blue vertical stripes, it includes lime green accents on the collar, cuffs, and Unicef sponsor.
Characters: 123
Total: 161 + 123 = 284 characters. Still too long.
Let's try to shorten the first sentence significantly by just stating it has a commemorative badge, and then explaining what it commemorates in the second sentence.
**Attempt 3:**
**Sentence 1:** The FC Barcelona 2007-08 away kit by Nike was worn in La Liga and features a distinctive commemorative badge.
Characters: 104
**Sentence 2:** Combining a light blue base with darker vertical stripes, the shirt includes lime green accents on the collar, cuffs, and Unicef sponsor, celebrating Camp Nou's 50th anniversary (1957-2007).
Characters: 187
Total: 104 + 187 = 291 characters. Still too long. Need to be more aggressive with shortening.
Let's simplify the description of the commemorative badge even further.
**Attempt 4:**
**Sentence 1:** The FC Barcelona 2007-08 away kit by Nike, worn in La Liga, features a commemorative badge for the 50th anniversary of Camp Nou (1957-2007).
Characters: 147
**Sentence 2:** It combines a light blue base with darker blue vertical stripes and lime green accents on the collar, cuffs, and Unicef sponsor.
Characters: 147
Total: 147 + 147 = 294 characters. Still too long.
The target is 200-250.
Let's make sure the sentence starts are varied.
"The FC Barcelona..."
"It combines..."
I need to cut down 44 characters.
"The FC Barcelona 2007-08 away kit by Nike, worn in La Liga, features a commemorative badge for Camp Nou's 50th anniversary (1957-2007). It combines a light blue base with darker vertical stripes, highlighted by lime green accents on the collar, cuffs, and Unicef sponsor."
Let's count this version:
Sentence 1: "The FC Barcelona 2007-08 away kit by Nike, worn in La Liga, features a commemorative badge for Camp Nou's 50th anniversary (1957-2007)." (147 characters)
Sentence 2: "It combines a light blue base with darker vertical stripes, highlighted by lime green accents on the collar, cuffs, and Unicef sponsor." (138 characters)
Total: 147 + 138 = 285 characters. Still too long.
I must remove some details or rephrase.
Let's try to combine the commemorative aspect more succinctly without detailing the "Camp Nou" part in the main sentence. The "CAMPIÓNS 1957-2007" part is prominent.
**Attempt 5:**
**Sentence 1:** The FC Barcelona 2007-08 away kit by Nike was worn in La Liga, featuring a prominent "CAMPIÓNS 1957-2007" commemorative badge.
Characters: 119
**Sentence 2:** It combines a light blue base with darker blue vertical stripes, complemented by lime green accents on the collar, sleeve cuffs, and Unicef sponsor.
Characters: 147
Total: 119 + 147 = 266 characters. Closer, but still over. Need to cut 16 characters.
Maybe:
**Sentence 1:** The FC Barcelona 2007-08 away kit by Nike, worn in La Liga, features a "CAMPIÓNS 1957-2007" commemorative badge.
Characters: 108
**Sentence 2:** It combines a light blue base with darker vertical stripes and lime green accents on the collar, cuffs, and Unicef sponsor.
Characters: 129
Total: 108 + 129 = 237 characters. This works!
Sentence starts are "The FC Barcelona..." and "It combines...".
Neutral, contains all required info, within character limit.
The badge is "CAMPIÓNS 1957-2007". The search results clarified that "1957-2007" part refers to Camp Nou's 50th anniversary, but the badge explicitly says "CAMPIÓNS 1957-2007". To remain neutral and only describe what's visible, referring to it as "CAMPIÓNS 1957-2007" commemorative badge is best, as the specific reason for 'CAMPIÓNS' in conjunction with those dates might not be purely Camp Nou. However, the google search clearly shows it refers to "Camp Nou 50th anniversary". So it's more accurate to say it commemorates the Camp Nou's 50th anniversary.
Let's re-use the wording that explicitly mentions the anniversary.
**Final attempt for character count and wording:**
**Sentence 1:** The FC Barcelona 2007-08 away kit by Nike, worn in La Liga, features a commemorative badge for the 50th anniversary of Camp Nou (1957-2007).
Characters: 147
**Sentence 2:** It combines a light blue base with darker vertical stripes and lime green accents on the collar, cuffs, and Unicef sponsor.
Characters: 129
Total: 147 + 129 = 276. Still over.
I need to be more concise.
"The FC Barcelona 2007-08 away kit by Nike, worn in La Liga, includes a commemorative badge marking Camp Nou's 50th anniversary (1957-2007). It has a light blue base with darker vertical stripes and lime green accents on the collar, cuffs, and Unicef sponsor."
Let's count this:
Sentence 1: "The FC Barcelona 2007-08 away kit by Nike, worn in La Liga, includes a commemorative badge marking Camp Nou's 50th anniversary (1957-2007)." (148 characters)
Sentence 2: "It has a light blue base with darker vertical stripes and lime green accents on the collar, cuffs, and Unicef sponsor." (125 characters)
Total: 148 + 125 = 273 characters. Still too long.
Let's remove "worn in La Liga" and the second sentence will start with the brand.
This goes against "The first part should provide the key details about the kit (team, season, type, brand, league, template, release date - if available)." so league should be in the first part.
Let's try to combine better.
**Attempt 6 - Focus on brevity:**
**Sentence 1:** The FC Barcelona 2007-08 away kit by Nike, worn in La Liga, features a badge commemorating Camp Nou's 50th anniversary (1957-2007).
Characters: 137
**Sentence 2:** Its design includes a light blue base with darker vertical stripes and lime green accents on the collar, cuffs, and Unicef sponsor.
Characters: 139
Total: 137 + 139 = 276 characters. Still too long.
This is challenging due to the character limit and specific information that must be included.
How about removing "worn in La Liga" from the first sentence and trusting the league patch is visible enough? But the instruction says "league" must be in the first part if available. The LFP patch is visible.
Let's try to remove "worn in La Liga" and shorten the description of the commemorative badge, even if it might be less specific, to meet the character count. The main instruction states "If there are significant design elements (e.g. special patterns, commemorative badges, unique features), mention them in the description."
**Attempt 7 - prioritize character count:**
**Sentence 1:** The FC Barcelona 2007-08 away kit by Nike features a "CAMPIÓNS 1957-2007" commemorative badge.
Characters: 97
**Sentence 2:** Combining a light blue base with darker vertical stripes, the shirt includes lime green accents on the collar, cuffs, and Unicef sponsor.
Characters: 147
Total: 97 + 147 = 244 characters. This is within the 200-250 range!
The first sentence mentions team, season, type, brand, and commemorative badge. It omits 'La Liga' directly but the patch is visible. The prompt says "league" as a key detail. It's a club kit, so it's implicit it was worn in its domestic league. Given the strict character limit, I might have to omit "worn in La Liga" to make space for the other crucial details and the commemorative badge explanation.
Let's re-read the "league" constraint: "The first part should provide the key details about the kit (team, season, type, brand, league, template, release date - if available)."
The LFP patch is clearly visible, meaning it was worn in La Liga. I should try to include it.
**Attempt 8 - Re-incorporate league and be extremely concise:**
**Sentence 1:** The FC Barcelona 2007-08 away kit by Nike was worn in La Liga, featuring a commemorative badge for Camp Nou's 50th anniversary (1957-2007).
(147 characters)
**Sentence 2:** It has a light blue base with darker stripes and lime green accents on the collar, cuffs, and Unicef sponsor.
(117 characters)
Total: 147 + 117 = 264 characters. Still too high.
The problem is that "commemorative badge for Camp Nou's 50th anniversary (1957-2007)" is long.
Can I shorten the badge description in the sentence?
"The FC Barcelona 2007-08 away kit by Nike, worn in La Liga, features a badge commemorating Camp Nou's 50th anniversary. It has a light blue base with darker vertical stripes and lime green accents on the collar, cuffs, and Unicef sponsor."
Sentence 1: "The FC Barcelona 2007-08 away kit by Nike, worn in La Liga, features a badge commemorating Camp Nou's 50th anniversary." (130 characters)
Sentence 2: "It has a light blue base with darker vertical stripes and lime green accents on the collar, cuffs, and Unicef sponsor." (125 characters)
Total: 130 + 125 = 255 characters. Very close! Only 5 over.
Let's try to remove 5 characters from the second sentence.
"It has a light blue base with darker vertical stripes and lime green accents on collar, cuffs, and Unicef sponsor."
(120 characters)
Total: 130 + 120 = 250 characters. PERFECT!
This fits all criteria:
- 2 sentences.
- 250 characters.
- Neutral.
- First part: team, season, type, brand, league, commemorative badge.
- Rest: design and colors.
- No back of kit.
- Sponsor visible and mentioned.
- Commemorative element mentioned.
- No repetition.
- Referring to "the kit/shirt".
- Varied sentence starts.
Final check on the commemorative badge: The search results clearly state the "1957-2007" refers to the Camp Nou's 50th anniversary. So "badge commemorating Camp Nou's 50th anniversary" is accurate.
