On November 15, 1969, as many as half a million people participated in coordinated marches on Washington, DC and San Francisco, the largest demonstrations during the Vietnam War. Organized by the Student Mobilization Committee (SMC) and the New Mobilization Committee to End the War in Vietnam (New Mobe), thousands of volunteers were recruited to provide transportation, food, housing and other logistics. This pinback was circulated as part of the organizational efforts leading up to the demonstrations.
