Authenticated and encapsulated by PSA/DNA, attractive signed 1939 Play Ball card of infielder Wayne Ambler, portrayed with the Philadelphia Athletics.  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.
