Whether you mail them or display them, you’ll want to pick up a set or two of these postcards; a striking visual legacy of Northern California activism. Released in conjunction with the “Art of Resistance” exhibition which displays the art from social change movements across the decades. The six cards in this pack showcase a different artist’s work, including A.M. Boyle’s suffrage poster, James Maxwell’s anti-war “Facts” doodle from Mendocino’s napkin art era, J.D. Mayhew’s “Whale War” poster, John Hewitt’s contemporary watercolor of a Fort Bragg protest, the Peace Fair poster by Jacques Helfer, and a “No Oil” poster by an unknown artist.
