Thirty years after a then-unknown 20-year-old model bared all, a new exhibition of photographs opens in London.

Touting itself as “The most intriguing, controversial and sexy art gallery in the U.K.,” Brighton’s Impure Art is an outlet for erotic art, or as stated on its Web site, “anything from nude to rude.”

The works, which are being offered for sale at £3,400 a print, are exhibited to coincide with the London dates for her Sticky & Sweet tour. Posing for Martin M. H. Schreiber’s photography class at New York ‘s Parsons School of Design in 1979, when she was 20 years old and fresh to the city, Madonna was paid $30 to model nude. Of course this was before the start of her music career.
