The collection also includes a few items created for the Women's March on Washington, as well as information on the various marches produced by march organizers, information about the Valentines to Congress project and the Pussyhat Project, photographs used in USC Libraries' Special Collections exhibit on the Women's March (Spring 2017), a few newspapers and magazines documenting the events, and miscellaneous notes that accompanied many of the items. Many of the posters include the names and hometowns of the marchers (information collected when possible at time of donation).
