William Thomas Hamilton (1822-1908) began his career as a trapper in the wilds of the Northern plains. He became a fixture in the territory and adept at communicating with many of the native tribes. Following the mid-19th century decline of the fur trade, Hamilton employed his extensive knowledge of the region and its inhabitants in the service of the U.S. Army, and he was an outstanding scout and fighter in the years leading up to the Great Sioux War of 1876. Former cowboy Charles M. Russell (1864-1926) ranks among the greatest of Western artists. He illustrated many books, including those of Theodore Roosevelt and Owen Wister's classic, The Virginian. Sixty Years was among his earliest works, and the paintings reproduced in this edition are signed with his name and his personal symbol, a buffalo skull.
