No, not autograph. Automobile.
I don't know where I got this pack, but I've had them for quite some time. In honor of the Indy 500 and the Coca Cola 600 I thought I'd open it.
My guess is that these cards were issued in conjunction with Alex Gabbard's book of the same name.
The backs, though informative, don't give much clue to the set of cards. The highest numbered card I pulled from this pack is V1-64.
