NOT a repro!...this original 1964 celluloid pinback button says I'M A BEATLES FAN and shows all 4 Beatles against a red background. Measures 3 1/2 inches across and rim is marked cNEMS ENT. LTD. 64 and GREEN DUCK CO. CHICAGO MADE IN USA. We've been dealing in original Beatles memorabilia since 1969...this button was leftover candy store stock when the Beatles split up. Near-mint condition.
