I still have my brochures from the 60s. They've travelled a good number of miles with me and I still refer to them in the car collecting hobby. One that looks like my 67 GTO convert is framed on the wall with the boastful Wangers' ad copy, too. It begins "GTO is an idea on wheels..."
I missed any mention of the two series of US postage stamps that Fitz was commissioned to do about 13-16 years ago. 50s Sporty Cars and 50s Fins and Chrome. Curiously, a Tom Fritz did the next batch of Musclecars stamps.
