Those pictures are beautiful. They cover everything from speed runs on the sand (Daytona?) Indy, landspeed. The pictures of the Summer's brothers FWD single engine car show how small it was, Atohl Grahams car and engine, I think there a couple of Mickey's 4 motor car. I plan to take some time and save them all for additional viewing. It would sure be interesting to know who's estate sold these truly priceless pictures.
