2” picturing beer stein at center inscribed “sic semper sick.” Ribbon design surrounding this is “Charter Member/Ever Cool.” Rim inscription is “The Beat Generation/Hipville, U.S.A.” Exceedingly tiny bump center right caused by bar pin on reverse but rest is Exc. and displays Mint. Button almost certainly pre-dates use of the term “Hippies.” Only one we’ve seen. Comes with Hake’s COA.
