9 3/4 x 11 3/4 in. unmounted albumen photograph. Housed in a modern frame with glass on both sides (not examined out of the frame). Uncredited. Verso bears miniscule pencil inscription reading "Bishop Whipple," likely referring to  Bishop Henry Benjamin Whipple (1822-1901), who acted as an advocate for Native Americans.

21 Native American subjects are featured sitting in rows, with Captain Richard Henry Pratt standing to the viewer's left. They pose outside of one of the fort's masonry buildings wearing sack coats and having what appear to be kepis or forage caps in their laps. Identities of the subjects provided by Karen Daniels Petersen's Plains Indian Art from Fort Marion (and obtained by us from the Smithsonian website), from front row to back row, left to right: Little Chief, Shave Head, Nick, Buzzard, Koba, Tounkeuh, Ohettoint, Captain Pratt, Tsadeltah, Matches, Buffalo Scout, Tsaitkopeta, Soaring Eagle, White Bear, Bear's Heart, Zonekeuh, Roman Nose, Squint Eyes, White Man, Cohoe, Making Medicine, and Zotom.

Several of those pictured likely went on to attend Carlisle Indian School, a project of Captain Pratt's where Native Americans learned to become "civilized" through work and education. One confirmed student of Carlisle featured here is Matches (or Carl Matches), who is best known for his ledger drawings he created while confined at Fort Marion.
