The old thick Fremont posters were a dime a dozen back then. I used to watch my dad cut them up on the kitchen table and make them into head gaskets.
These are great......I went to Detroit Dragway in the late 60's/early 70's.It was a NHRA sanctioned track then. It's gone now. I used to love to watch the pro stock and funny car match races. Wish I had some fliers to share.
