On a sunny Wednesday in June 1975, Chicagoans were treated to a rare sight: 10 Playboy Bunnies parading along Michigan Avenue in front of the Playboy Club, carrying picket signs. playboy policy is unfair to bunnies and free the bunnies were among the slogans. No one had ever seen anything like it: For one thing, Bunnies were forbidden from wearing their uniforms outside the club. The protest attracted instantaneous attention, stopping traffic and clogging the sidewalk. The gawking spectators were joined by reporters, photographers and TV news cameramen, with police officers rather halfheartedly trying to contain the Bunnies.
