All cards have the player name written or stamped on them. The written ones appear to be a child's handwriting (the handwriting even improves as the cards got newer), not an attempt at autograph forgery. The stamps are almost exclusively on Reds cards, leading us to believe that those were sent to the team for autographs, stamped there and returned. Besides the 1963 Mantle, There's a 1963 Aaron, a 1964 Rose and many other HOF'ers. Great novelty/placeholder lot.
