Christy Mathewson shown in his 1913-1914 World Tour sweater. This photo was likely taken in Marlin Springs, Texas during Spring Training 1914. The postcard was addressed to, and owned by, Mathewson himself. It was sent to him c/o the Giants at the Polo Grounds by a Texas newspaper reporter who had been at Spring Training with the Giants.
Take a look at the signature of the sender of the postcard.
The article below establishes the provenance of the postcard. Roy T. Cook was a reporter in Whitewright, Texas and was in Marlin for the Giants camp. This explains the Whitewright postmark and indicates this photo was no doubt taken in Marlin, Texas in March 1914 during Spring Training.
