1921 Exhibits Stan Coveleski, signed by Coveleski on the front. PSA has encapsulated the card and certified the signature as "Authentic." Coveleski's signature has been scripted in black fountain atop his image and grades 9/10. Signed exhibit cards are scarce, especially those of Hall of Famers such as Coveleski. This is the first signed example of this particular card we have ever handled and one of only four we have seen certified by PSA. The card displays surface paper loss, adhesive residue, and written notations on the reverse, as well as corner/edge wear and light surface marks. In Fair to Good condition overall.
