Two of America's greatest racing Driver's. AJ Foyt in the #6 Ford overhead four cam V-8. Mario Andretti in the Offenhauser powered #2. Both Indy Dirt Championship cars on the one mile dirt oval at Duquoin, Illinois.
I believe the light colored car at the left is a Rekord, while the four door being lowered is a 1958-ish Kapitan. Search results claim this was at GM's plant in Switzerland. I would expect that the rear leaf springs already had the bushings in place by that time.
