Thanks to Bill for sending in this scan. If anyone knows the original owner of this piece I’d love to know the story behind it. You can see the folds so maybe a fan mailed a letter to Marvel and asked for Stan and Jack’s autographs?
The artwork looks like several of the images were probably swiped from Kirby drawings. Rawhide Kid and Two Gun at the bottom look like they were probably paste-ups, but figures like the Hulk and Nick Fury look like they were done probably by an office staffer.
