This is a license plate frame from Don-A-Vee. The business name on the card is Don-A-Vee Rambler. The AMX and Javelin began production in late 1967, and American Motors changed its nameplate from Rambler to AMC in 1970.
Don-A-Vee Motors was a small dealership in a small California town. This is a diagonal view from the opposite corner of the intersection.
