There was always something special about Madonna, a certain appeal. Mostly it was her a-peel since she started stripping down for posed nude photos as soon as legally possible. Now naked photos of Madonna at the tender age of 18 are about to hit the auction block at Penthouse founder Bob Guccione’s estate sale.

Taken circa 1977 by photographer Herman Kulkens, the photos show University of Michigan dance student Madonna Louise Ciccone posing in an open men’s shirt, brushing another naked gal pal’s hair, and showing off the massive muffalotta that we’ve all come to know and love. Check out the Material Girl’s material curls. It’ll feel like you’re touching yourself for the very first time!
