"Muhammad Ali pierced by six arrows, posing as St Sebastian: the April 1968 Esquire cover was one of the most iconic images of the decade thanks to designer George Lois, tying together Vietnam, race and religion. Lois's magazine work was showcased in an exhibition at New York's MoMA last year and is soon out in book form. More than covers, they're provocative statements of political and cultural issues that are still relevant today." - Graham Sergeant
