Back cover art for a pulp magazine about cowboys. Arthur Roy Mitchell (December 18, 1889– November 1977) was an American artist and historian who was born on his father's homestead west of Trinidad in Las Animas County in southern Colorado. Usually known as "Mitch," Mitchell in 1907 began work as a ranch hand in New Mexico. Soon, he was sketching scenes of cowboy and western life and drawing political cartoons for newspapers. After United States Army service in World War I, he traveled to New York City, where he studied at Grand Central School of Art under Harvey Dunn. By 1940, he had created more than 160 cover paintings for Western pulp magazines. During the summers, Mitchell continued to paint in the American Southwest and often invited his mentor Dunn to come to Colorado to sketch the landscapes.
