Talkin' Baseball

Small photograph, it appears to be of a few folks posing for a portrait mid-baseball game.

On the back is some writing in pencil:

July 4th 1936

Found in "Dance of the Machines" by Edward J. O'Brien. Published by Macaulay, 1929.

Here's a large, cleaned-up version of the photograph:
