'Impressions for Change: 35 Years of Political Posters from Red Sun Press'

With $350, a small press, and a big mission, three political activists started Red Sun Press in 1974. Thirty-five years later, the print shop still supports political and social change focusing on peace, justice, and a sustainable world. "Impressions for Change: 35 Years of Political Posters From Red Sun Press," an exhibit of 26 posters reflecting the history of social change in Boston, features Kim Berman’s 1990 "Nelson Mandela" poster celebrating Mandela’s release from prison and visit to Boston. -- June Wulff, Globe Staff
