        "photo 1: No Coach wordmark, horse-and-carriage mark, creed patch, serial\/style number, or recognizable Coach hardware is visible.",
        "photo 1: The large decorative skull clasp and bright silver-tone hardware are inconsistent with typical vintage Coach construction, which generally used restrained solid-brass hardware on classic styles.",

        "photo 1: The rectangular studded shoulder-bag silhouette does not correspond to a recognizable vintage Coach model, and the skull ornament is not a Coach catalog identifier.",

        "photo 1: Condition appears approximately Very Good from the visible exterior, with no major damage apparent, but the wrapped strap and absent interior view prevent a complete grade."
