Playboy launched in December 1953 with a celebrity on the cover and in the pages-Marilyn Monroe (who didn't actually pose for the mag)-but the magazine really didn't trade in famous nudity for its first couple of decades. Movie icons, TV stars, athletes, supermodels-fans know them with their clothes on, and a lot of those fans want to see them with their clothes off. And as much as warm-blooded folks all like getting a peek at the Playmate-dreamed up by Hugh Hefner to be the girl next door, stripped bare for your convenience-nothing has the gawk factor of celebrity skin. Over the years a lot of hot, nude women have graced the pages of Playboy.
