A vintage promotional advertising item in the form of a traditional door key. The item is constructed of cast metal with a pebbled or sand-cast texture and a bright brass-tone finish. The circular head or bow features raised, cast serif lettering on the obverse. The blade is designed with a single longitudinal groove and deep bitting on one side, consistent in profile with standard mid-century padlock or locker keyways. A small circular hole is located at the top of the bow for attachment to a keyring. The reverse side is plain with a consistent textured finish and lacks any additional markings or stamps.
