    "possible_model_reasoning": [
        "photo 1: The rectangular shoulder-bag silhouette does not closely match a cataloged vintage Coach model, and the London-themed beadwork is characteristic of a novelty souvenir\/fashion bag.",

        "Condition: Like New or New\/NWOT based on the clean, apparently unused presentation and attached paper tag; interior and odor cannot be assessed from the photos."
