Madonna has never had much use for modesty. And evidence of her early exhibitionist ways went for more than double the expected price at auction Thursday.

Originally expected to fetch $10,000 to $15,000, the framed 1979 nude photograph of the pop singer was sold for $37,500 to an anonymous bidder. It was one of a series of photographs taken by photographer Lee Friedlander when Madonna was a cash-strapped student.

Friedlander reportedly paid her $25 for modeling for him. The pictures later appeared in a 1985 issue of Playboy.

Some people might be taken aback by the raw style of the photo. Madonna appears with hair under her arms and a very natural-looking pose void of the affectation of glamour that marks so many of her photographs.
