        "photo 1: No COACH wordmark, horse-and-carriage, hangtag, or other Coach identifier is visible.",

        "photo 4: No creed, serial, wordmark, or other brand identifier is visible."

    "possible_model_reasoning": [
        "photo 1: The silhouette is a generic structured top-handle handbag and does not closely match the listed vintage Coach classic models.",
        "photo 1: The seller's 1960s description is plausible as a broad style estimate, but the photographs do not establish a specific year or maker; the material and geometric design support only a broad vintage probability.",
        "photo 1 and photo 4: Condition appears Good\/Fair due to visible surface scratches, stains, creasing, and worn white material; the interior is dark and incompletely assessed."
