Anti-Nam Activist Roger May's Estate Pinbacks, Buckle & Lighter

I acquired a collection of artifacts from the late Roger May, a San Francisco Anti Vietnam protester / activist from the late 1960s into the 1970s. Among the pinbacks, belt buckle and lighter was this rare Hippie Era pinback supporting the Flower City Conspiracy... On September 6, 1970, the offices of the Selective Service, F.B.I., and the U.S. Attorney were ransacked during the early hours of Sunday morning. The eight anti-war Flower City conspirators were all convicted... I know with collectors condition is key, not here. These were all used by a known activist who took part in the FBI Building take over. Used with history of the era is what I want.
