Grok says: “Overall scene: This is clearly the entrance to a fish/seafood market or shop. The combination of the “FISH” sign, tuna/salmon references, and the Shanghai Aquatic Products Company notice all point to that. The cat sleeping right there makes perfect sense! Some text is faded, angled, or partially obscured by wear on the posters, so I can’t read every single character perfectly, but the main ones are clear. I examined the image closely (including the posters on the wall/door area). Here’s what the visible text says: Right-side posters (on the dark wall/door frame): Top poster/ad: “Great Low tar Vantage”
This is a vintage Vantage cigarettes advertisement. Vantage was known in the 1970s–80s for its “low tar” marketing with slogans like “Where Great Taste & Low Tar Meet.” The circular target-like logo next to it is typical for their ads.
White paper/poster below it:
上海水产公司 (Shànghǎi Shuǐchǎn Gōngsī)
→ Shanghai Aquatic Products Company (a real fisheries/aquatic products company).
经营 (jīngyíng) → “operating,” “managing,” or “for business/sale.” There are additional Chinese characters below that are partially faded or angled, but it appears to be an official notice or business sign related to seafood/aquatics.
On the glass door: Large sign: FISH
Lower section (partially visible): Mentions of Tuna and Salmon (or similar seafood items — looks like a shop menu or product list).
