Artist Joseph Yoakum
Joseph Yoakum (1891-1972) didn't start creating art until he was in his 70s. Self-taught in his use of ballpoint pens, colored pencil and pastels, Yoakum (who claimed Native American ancestry, and whose mother was a formerly-enslaved African American) created magical landscapes, now currently on view at New York's Museum of Modern Art.
