Albumen photograph, 5.25 x 7.25 in., on 11 x 14 in. Hayden Survey mount with credit at lower left to W.H. Jackson. A studio view of Lower Yanktonais Dakota Indian Bull's Ghost, or Ta-Tan'-Ka-Wa-Na'-Gi, originally taken by Alexander Gardner in 1872. Bull's Ghost served as Sitting Bull's mouth piece in the Ghost Dance exercises. Only having one eye, he was purportedly called "One Eyed Riley" by whites. (See James McLaughlin's memoirs, My Friend the Indian, p. 203.)
