The black-and-white poster shows Hana Nitsche, 25, posing naked, with the tagline: "Fur? I'd rather go naked!"
Nitsche follows in the footsteps of Pamela Anderson, Alicia Silverstone and Eva Mendes in supporting the animal rights group.
Though she has been modelling for four years now, she admitted that she still got nervous in front of the camera - particularly in the case of the PETA campaign.
"I get so nervous and shy, you would not even believe it's the same girl from the pictures," the Daily Mail quoted her as saying.
