Pair of prison league baseball photographs of the Booker T's and the White Sox, two teams from a prison league in Leavenworth, Kansas, the Booker T's with sixteen African American men in uniform, three prison men on the side, their catchers equipment and bats laid out in front of them, the White Sox with seventeen men in uniform, an umpire to their left and three prison men seated in front of them. The Leavenworth prison league officially began in 1912, under the watch of Deputy Warden William Mackey, with white men forming the Brown Sox, Native American men forming the Red Men and African American men forming the Booker T Washington's.
