1921 Exhibits Zack Wheat, signed by Wheat on the front. PSA has encapsulated the card and certified the signature as "Authentic." Wheat's signature has been scripted in black fountain to the right of his image and grades 6/10. Signed exhibit cards are scarce, especially those of Hall of Famers such as Wheat. This is just the second signed example of this particular card we have ever handled and the only example we have seen certified by PSA. The card displays a small area of surface paper loss in the upper left corner, surface paper loss and adhesive residue on the reverse, and both edge and corner wear. In Fair condition overall.
