        "photo 1: ornate patchwork construction with a large rhinestone\/filigree decorative centerpiece and fringe is not characteristic of the documented vintage Coach catalog.",

        "No Coach identifier is visible in the supplied exterior photos; the unseen interior prevents a complete identifier check."
