"There's a time when the operating of the machine becomes so odious, makes you so sick at heart, that you can't take part... And you've got to put your bodies upon the gears and upon the wheel, upon the levers, upon all the apparatus, and you've got to make it stop!" These words, shouted by the incendiary student leader Mario Savio at a free speech rally at UC-Berkeley in 1964, helped define a generation. Coupled with the war in Vietnam and the growing sense that the U.S. government no longer had the interests of its citizens in mind, Berkeley students led one of the loudest and most effective anti-government campaigns in American history. This special collection from the University of British Columbia features 250 posters from the protest movement. Often hand drawn, the posters are a powerful expression of the hope and bitterness of that tumultuous era.
