The Aztec - originally completed in about 1957 or 1958. It was on 9 different magazine covers in 1958 and was the sensation of the show circuit back then. I don't remember, since I was only one at the time.
When I saw another of your photos of this I thought it looked familiar. I probably had some of those magazine since at that time I would buy Car Craft, Custom Cars and Rod and Customs every month. V for the photo and the memory revival.
