Hall of Fame pitcher Carl Hubbell applied his familiar angular signature to the bottom right of this 1940 Play Ball card, the signature earning a MINT 9 from PSA/DNA on this VG-EX example.  The card originates from the Shibe Park collection of autographed cards, an original owner collection carefully collected by a teenage boy who, in 1939 and 1940, obtained many autographs from players arriving at the train station near Shibe Park, and continued for many years to obtain signatures in person and through the mail.
