Roy "Pop" Joiner owned a very brief major league career, pitching 22 games for the Cubs between 1934 and 1935, and returning for 30 more with the 1940 Giants.  His 1940 Play Ball card has been signed and authenticated by PSA/DNA.  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.
