Adelaide's Progressive Art Movement (PAM), born out of Flinders University and spearheaded by radical thinkers Brian Medlin and Ann Newmarch, united artists, writers, poets, filmmakers, actors and musicians determined to cultivate a politically progressive culture rooted in local issues, while vehemently opposing US imperialism.

Five decades on, Catherine Speck and Jude Adams tell PAM's little remembered story. They unearth powerful posters and prints by artists including Ann Newmarch, Mandy Martin, Robert Boynes and others, whose work spread messages of community action, resistance and solidarity.

If You Don't Fight ... You Lose: Politics, posters and PAM celebrates the enduring power of political printmaking: a timely theme for our tumultuous twenty-first century.
