Sorry Guys, but some of the YSE prints were full signature print I have 2 friends that have them. In the 70's you picked the prints that you wanted from a stack and I remember then their were a few full sigs in 1 of the stacks (if I only knew.) Back then $35.00 ea or 3 for a 100.00. At least all the ones I have are signed on the back. AA prints where next then came no signatures or AA. I am not sure what the current price is for YSE print must be up to $125.00 to 150.00 still the best deal in the park.
