This is a vintage key chain proudly made in the United States by Highland Glen Manufacturing Incorporated of Buffalo, NY.  This oblong keychain/key ring was produced under licensing and features a multi-color Cadillac design with a matte black ruffled edge and gold lettering.  The keychain measures approximately 3 1/2 inches long with the ring (about 2 3/8 inches with just the fob piece) and is about 1 inch long.  This keychain comes as photographed.  It is new in it's original packaging.  However, because the packaging does show signs of wear and discoloration, I removed the keychain to make sure it was in good condition.  Due to years of storage the jump ring (ring that connect the key ring and the fob) does have some rust.  Please see last two photos for close ups of this area.  The back side of the keychain is just a simple solid black color.  Please review and enlarge all photos for additional details, views and measurements. If I had to date this, I would say it was from the 1980's or 1990's.  Shipped via USPS Ground Advantage.
