        "photo 1: Clearly a leather handbag with a vintage-style metal frame handle and structured envelope silhouette.",

        "photo 1: No legible Coach wordmark, horse-and-carriage logo, or recognizable Coach hangtag is visible.",

        "photo 6: A straight-on, close-up photograph of every interior label, stamp, or leather patch is needed; the visible interior area is too dark and oblique to read.",

        "Photos of the bottom, side seams, corners, and any remaining tag or zipper-pull markings are missing.",

    "authenticity_concerns": [
        "No Coach identifier is visible in the supplied photos, so this currently reads as a generic vintage leather handbag rather than an identifiable Coach piece.",
        "The lined envelope\/frame construction and generic hardware do not provide the usual evidence for a classic glove-tanned Coach bag; this is a lookalike risk, not proof of a replica."

        "The envelope shape, metal frame handle, and approximately 12-inch width do not clearly match a cataloged classic Coach model; no Coach model is proposed without an identifier.",
