        "photo 1: The bag is a structured handbag, but no Coach wordmark, horse-and-carriage, creed, hangtag, or other Coach identifier is visible.",

        "photo 6: No Coach identifier is visible in the available interior view, and the apparent synthetic lining\/materials do not fit a classic vintage Coach construction."

        "Condition: Fair\/rehab; photo 3 shows substantial handle peeling, while the seller also reports outer-material peeling, hardware wear, and interior wear."
