Crista Flanagan’s nude Playboy magazine pictures are making a splash… look for naked pics of the “Mad Men” star in a retro photo shoot in Playboy’s August 2010 issue.

Crista Flanagan, who plays switchboard operator Lois Sadler on “Mad Men,” is featured topless on the cover of Playboy, with just a tie – and strategically placed arms.

Crista Flanagan is recreating a 1960 cover of Playboy, and inside the issue, her entire nude spread are recreations of 60s pinup girls.

Crista Flanagan said of the nude Playboy pictures: “I really did feel like I was re-creating something and that I was bringing to life these women who already posed for Playboy in the ’60s. If I tell a friend I did this, they think I’m completely naked. … This was not Crista filling your wish list out. This was trying to capture an era.”
