This image of Bresnahan was shot against the infield wall at the Polo Grounds in circa 1905. It is part of a series of shots showing Bresnahan going into his crouch. It is reminiscent of the Mathewson sequence done by John C. Hemment. It has a Paul Thompson stamp, but as Thompson was not a photographer and used other photographer’s images I believe it is likely an image taken by Hemment. The “3368/3” on the back in pencil would represent the image number in Hemment’s photo album with the “3” representing the 3rd image in the sequence.
