Correspondence, together with articles and biographical notes assembled for an article about army surgeon Henry Rinalda Porter, who participated in the Battle of Little Big Horn; also photographs of the battlefield and participants in the conflict.

Henry Rinalda Porter research materials include Cutter's correspondence (1931-1934) with various individuals, including battle participant E.S. Godfrey. There is also extensive correspondence with North Dakota and Wisconsin photographer D.F. Barry, who photographed many of the Indians who participated in the Custer fight. In addition to discussing the battle, these letters reveal much about the later years of D.F. Barry and are accompanied by many brochures and advertisements of his photography business.

Custer battlefield photographs include views of soldiers' death site markers, the battlefield monument, and the adjoining national cemetery. There are also images of the Big Hole battlefield, Fort Abraham Lincoln, Fort Berthold, and Fort Union, and portraits of Curley (Custer's scout), E.S. Godfrey, Henry Rinalda Porter, and Sitting Bull.

Also a Feb. 24, 1888 letter from George Crook to Perry, Mason & Co. regarding articles on his frontier experiences for Youth's Companion, and pencil sketches of western scenes by Charles M. Russell.
