I stumbled on this website late last week. I'm not much of a Nascar fan, but I have to admit I spent most of the weekend looking through the pics from the 60s and 70s. He must have scanned every pic from every source imaginable. Lots of fascinating stuff - especially the races in '63 and '64 with the Holman-Moody Galaxies.
