        "photo 1: the shoulder-bag silhouette is a generic late-1990s\/2000s fashion style and does not closely establish a Coach catalog model.",

        "Condition: Good; visible scuffing and surface wear on the black trim and strap (photos 2 and 4), with interior condition only partly shown (photo 5)."
