Journeyman infielder Don Heffner signed this 1940 Play Ball card in blue, the signature strong enough to garner a grade of NM-MT 8 from PSA/DNA.  A vertical crease is visible along the right third of the card, one of the only cards from this collection so marred.  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.
