In November 1991, she donated them to Hampshire College.The collection consists of posters, photographs, calendars, buttons, banners, and related monographic and periodical material representing anti-war and other protest movements of that time. Of particular note are the many posters in the collection by Sister Corita (Sister Mary Corita Kent), as well as a book about her housed in Box 6. The collection is arranged by type of material.
