        "photo 1: Listing describes the bag as PU\/vegan leather, which is inconsistent with the typical vintage Coach glove-tanned leather population.",

        "photo 3: Small gold-tone exterior logo does not visibly read COACH.",
        "photo 4: Interior has a printed synthetic-looking lining and zipper pocket, not the unlined suede interior typical of many classic vintage Coach bags.",
        "photo 5: Product-style size graphic and coordinated pouch indicate a modern mass-market tote rather than a vintage Coach item.",

        "strap_construction": "photos 1-3: Two long, thin dark flat shoulder handles attached directly to the tote; no adjustable or detachable vintage Coach strap is visible.",
        "stitching_description": "photos 1-3: Straight machine stitching is visible along the upper edge and color-block seams; fine construction details are limited by the product-photo format."

    "possible_model_reasoning": [
        "The rectangular open-top tote with double handles and matching pouch does not closely match the listed vintage Coach classic models.",

        "Condition: Like New or new-product condition in staged photos; no meaningful wear assessment is possible from these images."
