Richard Henry Pratt and a Group of Former Students, c. 1903

Group portrait of Richard Henry Pratt with a large number of male and female Native Americans and a few white people. There are some children in the group. 

Among the group is former student White Buffalo, and it seems likely this is a group of former students who returned, along with Pratt, to attend the school's commencement in 1903, as described in this issue of The Red Man and Helper: RedMan-Helper_v03n26-n27.pdf (dickinson.edu)
