Restoration of "The Custer Fight" (1903) by Charles Marion Russell (1864-1926). Lithograph showing the Battle of Little Bighorn, from the Indian side, showing the Lakota and Northern Cheyenne. As an American work from before 1923, the original is out of copyright.
This is part of the romanticization of the Wild West in the early 20th century; I shouldn't like to claim any sort of strict historical accuracy for it without researching the particular point for which accuracy is claimed - I'm not an expert on Indian clothing, nor on the tactics of the Indians at the Battle of Little Big Horn (a.k.a. Custer's Last Stand). Nonetheless, as art, it's gorgeous.

No restoration notes, because, frankly, this was one of my Wikipedia restorations before I left there, and I don't really remember. The brief notes I wrote at the time make it sound fairly standard.
