The Peace Collection Posters contains approximately 4,500 items, some of which were removed from various collections in the Peace Collection and some of which were donated independently.

Ruth Pearce was a professor of Russian at Bryn Mawr from the 1950s-1970s. The collection has not been dated, but can be inferred to primarily consist of materials from the 1950s-1970s. It consists mostly of works related to the Russian language and culture, and Pearce’s manuscript.
