The White Cloud, Head Chief of the Iowas by George Catlin https://www.nga.gov/artworks/50655-white-cloud-head-chief-iowas
During the 1830s, traveling with fur company representatives, cavalry officers, and later alone on multiple western journeys, George Catlin gathered drawings, sketches, and notes that would allow him to create an “Indian Gallery”—a collection of more than 500 paintings of American Indians. By the end of the decade, he would be widely recognized as the most celebrated painter of America’s native people.
