Catlin describes Iron Horn as a warrior, in a splendid dress (1848 catalogue, p. 20).
Painted at Fort Union in 1832. Certain Blackfoot portraits are closely related to the Sioux series. Catlin apparently confused the names of Iron Horn and Buffalo's Child when identifying plate 16 in Letters and Notes. Iron Horn also appears, full length, in cartoon 38, in a different pose and costume.
