2018 has seen untrained artists surge at major American museums, with the group exhibitions Outliers and American Vanguard Art at the National Gallery of Art and History Refused to Die at the Met, and the upcoming retrospective Between Worlds: The Art of Bill Traylor at the Smithsonian American Art Museum (SAAM). Leslie Umberger, SAAM’s curator of Between Worlds spoke with artist Kerry James Marshall, who wrote the introduction for the accompanying monograph on Traylor.
