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 New Mobilization Committee to End the War in Vietnam (New Mobe) and the Student Mobilization Committee to End the War in Vietnam (SMC), thousands of volunteers were recruited to provide transportation, food and housing, and other logistics. This pinback was circulated as part of the organizational efforts leading up the demonstrations.
