        "photo 1: the lot shows three handbags, but none displays a visible COACH wordmark, horse-and-carriage, creed patch, or recognizable Coach hardware.",

        "photo 1: the animal-print bag uses extensive silver-tone decorative hardware, contrast stitching, and mixed synthetic-looking panels unlike classic vintage Coach construction.",
        "photo 2: the animal-print bag has an oversized decorative buckle and numerous studs; this is a generic fashion-bag design rather than a catalog Coach silhouette.",
