This is the sole signed 1939 Play Ball in the PSA/DNA pop report for Jack Wilson, who pitched nine seasons in the American League primarily with the Red Sox, as depicted here on his 1939 Play Ball. Signed boldly in black, this is a fantastic autograph with some character to it. PSA/DNA obviously agrees with the grade of Gem Mint 10 for this signature.  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.  Though there is significant paper loss on the reverse, the product of scrapbook removal, more interesting is the date applied to the reverse.  July 5, 1939 was a getaway day for Boston, though they defeated Philadelphia, 6-4.  Wilson did not pitch that day, though he pitched two innings of shutout relief the day before, in an 18-12 slugfest won by Boston.
