Singer Madonna’s nude photos from her controversial coffee table book, Sex, which was released in 1992, are set to be sold at auction. The “titillating” pictures were taken when the star, then 34, was in New York and Miami and could fetch as much $30,000.

The pictures will be sold at Christie’s New York and will be signed by Madonna, now 64, and renowned photographer Steve Meisel. Prices for the photos begin at $49,000 and feature the Material Girl star in her birthday suit, posing everywhere from burlesque hotels to the beach.
