        "photo 1: no legible COACH wordmark, horse-and-carriage mark, or recognizable Coach hangtag is visible.",

        "photo 1: black bead-like decorative hardware around the flap and the braided strap are not characteristic of the documented vintage Coach classic construction.",

        "photo 1: the visible decorative hardware appears dark and bead-like rather than the solid brass hardware typical of many classic Coach bags."

        "photo 1: the flap shoulder-bag silhouette does not closely match the documented City Bag, Court, Willis, Dinky, or other recognizable vintage Coach models.",
        "photo 1: the absence of a creed and the non-Coach decorative treatment make a Coach model assignment unsupported.",
        "photos 1-6: condition appears Good overall because the leather has substantial creasing, scratches, scuffs, and strap wear; interior condition and odor are unknown."
