I found this tag stored with the original paperwork with my 67 RS. It's heavy paper with metal rivets. The POP confirms Courtesy Chevrolet in San Jose California was the dealer where it was sold new. I have never seen another tag like this and was just wondering what it was for.

The stock number assigned to each car at the dealership.
