In the Art Gallery in January: “World War I: Lessons and Legacies.” This is a free exhibit from the Smithsonian Institution Traveling Exhibition Service and the National Museum of American History. The exhibit explores the often overlooked aspects of Americans’ role in the Great War and many of the innovations, complexities, and contradictions in a post-war world that seemed so suddenly modern.  The traveling exhibit is supplemented with local interest material from the Olean Times Herald.
