This black and white studio photograph shows Chief Two Strike (Nomp Karpa) wearing an animal hide shirt decorated with beading on the sleeves and the front. There are two feathers in his hair, and he holds a tomahawk in the crook of his left arm. The photograph was taken at the Rosebud Reservation.
Some put Two Strike's birth date at 1821 and death date at 1914. He played an important role in the raids on the Union Pacific Railroad during Red Cloud's War (1866-1868). He was a member of a Sioux delegation to Washington, D.C., after the Wounded Knee Massacre in 1890. The Rosebud Sioux Indian Reservation is located nine miles north of Valentine, Nebraska, in South Dakota. Two Strike lived in the Two Strike's Camp Agency District.
