This collection, compiled by artist and activist Anson Seeno, consists of posters, fliers, and other graphic materials representing activist movements in Nicaragua and El Salvador, against gentrification and combatting homelessness in New York City, the politics of AIDS and U.S. governmental politics. Many of the posters date from the 1980s.

The New School Art Center was established in 1960 with a donation from the Albert J. List Foundation, and remained in operation until 1973. Directed by Paul Mocsanyi, the Center reflected The New School's commitment to engage provocative subjects, using art to explore contemporary issues. The collection contains sound recordings of events sponsored by the Art Center, often in conjunction with an exhibition or as part of educational programming.
