1925 Exhibits Harry Hooper, signed by Hooper on the front. PSA has encapsulated the card and certified the signature as "Authentic." Hooper's signature has been scripted in black fountain across his image and grades 7/10. Signed exhibit cards are scarce, especially those of Hall of Famers such as Hooper. This is the first signed example of this particular card we have ever handled and the only example we have seen certified by PSA. The card displays a large diagonal crease in the upper right corner, a few smaller creases, edge/corner wear, and areas of surface paper loss on the reverse. In Fair condition overall.
