This black leather key case has space for 3 keys.  It is from Hubacher Cadillac in Sacramento and is probably from the 1970s or 1980s.  It has a 5-digit zip code (so 1963 or later) and room for 3 keys.  Most Cadillacs had 2 keys in the 1980s and early 1990s before the electronic keys were created, one for the car and a separate one for the trunk.  This key case in 3-1/8" tall.  Minor wear on snap and logo, from smoke free home.
