Playboy Club Vintage Pictures

Octogenarian Hugh Hefner shows no signs of slowing down, and neither does the Playboy Club brand he introduced 51 years ago. The club Gloria Steinem calls "one of the tackiest places on earth" has made its way back into the public consciousness first as a cameo in Mad Men and now thanks to a new NBC show about its prime in 1960s Chicago.

Now Playboy has plans to get in on the nostalgia by opening a Chicago Playboy Club down the street from the original, which shut down two decades ago. It will likely open sometime next year.

The Playboy-style objectification is already alive and well at Playboy Clubs in London, Las Vegas, and Cancun. Whilewe would never call the job of a bunny inherently empowering, when you compare the concept to modern strip clubs, the retro joints almost seem modest. Let's just hope that they don't require pelvic exams and STD screenings as they did when Gloria Steinem went undercover as a bunny in 1963. See some vintage photos now of the Playboy Club.
