Hale Woodruff is regarded as one of the most important African-American artists of the 20th century. His best-known works are six very large murals he painted for the Talladega College library in the 1930s. An exhibition of the murals, along with early works from Woodruff’s career, opens this Saturday at the Birmingham Museum of Art. WBHM took a tour of the show this week with curators Kelli Morgan and Graham Boettcher.
