Royal Robertson, a visionary artist and self-proclaimed prophet, was born, lived, and died in Louisiana. He worked as a sign painter and field hand before turning to painting "visions" after the breakdown of his marriage. His artwork drew heavily from mass media sources such as television, comic books, and advertising, combined with fierce messages from evangelical Biblical stories and his personal beliefs. Robertson's work has been featured in various exhibitions and is held in prominent public collections like the Smithsonian American Art Museum, the American Visionary Art Museum, and the Minneapolis Institute of Art.
