Maureen Doallas' posts a fascinating video from American Public Media's OnBeing, "in which the Smithsonian ethnographer Candace Greene, collections and archives resource officer for the Smithsonian National Museum of Natural History, offers her insightful commentary on 22 drawings or pictographs made by Sitting Bull."

The drawings, "were created by Sitting Bull during his incarceration at Fort Randall, Dakota Territory in 1882 and are archived at the Smithsonian."
