SSOC operated as the defacto arm of Students For A Democratic Society (SDS) in the American South and was allied w/the Student Non Violent Co-ordinating Committee (SNCC). Comprised of civil rights activists, the group was also active in opposing the Vietnam War. The group saw itself as distinctly Southern and utilized images of the Confederate flag as found on this trio. The design on these buttons is by SNCC artist Claude Weaver and was fashioned after a handshake between SSOC organizer Archie Allen and SNCC chairman John Lewis. See lots #532-533 for additional SSOC buttons.
