My father went to art center, then onto GM TO co- design the trans am and the Cadillac Seville. I currently have two original renderings that were featured in design quarterly? I think that is the magazine. I’m interested in selling them but don’t know how. I also have a 5’x 3’ Watercolor of a hot rod show in Connecticut from the 80’s there is a guy on a victory bike in front of the cars. Any advice?
