Though Hall of Famer Travis Jackson hung up his cleats as a player at the end of the 1936 season, he continued on as a minor league manager through 1960.  One of the best shortstops of his time, Jackson finished his career with a .291 lifetime batting average, hitting .300 six times and spending his entire career with the Giants.  He was inducted into the Hall of Fame in 1982 by the Veterans Committee, an outstanding defensive shortstop.  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.
