The picture with the attendant discarding the Velvet cans has the oldest Speedway patches on his shirt & hat that I have ever seen.
It looks like the patches say "Speedway 70" but the car looks to be from the 1950's.
Before Speedway 79 & Speedway 77, Speedway was marketed as Speedway 70.

Super neat picture that I have never seen before !!
