This is a complete 82 card set. All cards have blank backs.
No cards have been die cut. Some cards have tape marks on the back.Some cards have wrinkles, worst two cards are 1a and 1b, most are NM to Mint otherwise. 1a is also unstuck from its back (back is still with the card though).
Story goes that these were part of the original run to test printing methods and the backs were not printed on them. There is zero evidence of die cut marks or anything else to suggest they are forgeries.
I have shown these to Topps employees and they agree they are authentic and that there were runs in the beginning that produced only fronts without die-cuts but most were thrown away. Incredible set and I've never seen another like it. These are not fake or reproductions.
