This is a very nice illustration of a 1965 Chevy convertible that has faded a bit but still shows what was possible back then. I think it was intended for an outdoor board but could have been used for a magazine or catalog illustration too. Wish I knew who did the work--could have been one of the fine West Coast illustrators or one of the Detroit group. There was lots of demand for this kind of work then and there were quite a few artists capable of this degree of excellence.
