Hagley Museum and Library in Wilmington

Little-known fact: The library at Hagley holds the records of the U.S. Chamber of Commerce, says the museum’s Meg Marcozzi. Hence “100 Years of Picturing the Nation’s Business: Photographs from the Collection of the Chamber of Commerce of the United States of America,” which celebrates another centennial. The exhibition shows photos of significant moments such as reaction to the stock market crash, aftermath of the Dust Bowl and news of the Titanic sinking. (Wilmington, 658-2400, hagley.org)
