        "photo 1: prominent exposed zippers and several decorative leather zipper pulls do not show a Coach wordmark, carriage, or other identifier.",
        "photo 2: no Coach branding is visible on the exterior or hardware.",

    "authenticity_concerns": [
        "photo 1-5: no Coach identifier is visible, and the contemporary multi-pocket design and dark plated hardware provide no support for Coach manufacture.",
        "photo 1-5: listing photos appear like clean product\/catalog images for a new unbranded bag, which is inconsistent with the usual presentation of a vintage Coach find."

        "The silhouette does not closely match the listed vintage Coach classics and lacks their typical turnlock, structured flap, or identifiable construction cues.",

        "Condition: Like New\/NWOT based on clean product-style photos and no visible wear; interior and functional condition are unverified."
