Emmett "Heinie" Mueller had a brief major league career, just four seasons with the Pirates, during which time he batted .253.  Mueller enlisted in the US Army just after Pearl Harbor, serving four seasons in the military.  After the war concluded, Mueller attempted to try out with the Phillies, but having missed so much time, he did not latch on with the club, and played minor league ball until his retirement. His signature on this card has been graded MINT 9 by PSA/DNA, a rich, dark application. 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.
