        "The cylindrical zip-top crossbody shape is not a close match for the documented vintage Coach City Bag, Court, Willis, Dinky, Station, or other listed classic styles.",

        "Condition: Very Good based on the clean exterior and intact-looking strap and zipper; interior condition is only partly visible, so lining condition and odor are unknown."
