AceShowbiz - Prints of Madonna's "SEX" book photographs are listed for auction. The 64-year-old pop icon put out the coffee table book back in 1992, and Christie's - the world-renowned auction house - has now confirmed that the snaps are poised to go under the hammer.

"Christie's is pleased to announce its participation in the ongoing anniversary celebration initiated by Madonna and Saint Laurent's re-issue of 'SEX', the boundary-pushing 1992 photography book by Madonna and Steven Meisel," Christie's said in a statement.

"As part of the project, Christie's will present Madonna x Meisel - The Sex Photographs an auction of over 40 works, as editions of one, in a live sale taking place in New York on October 6, 2023."

Madonna has also taken to Instagram to announce the news. The "Vogue" hitmaker explained that proceeds from the auction will go to Raising Malawi, a non-profit organisation that is changing the lives of children in Malawi through "health, education and community support."

Madonna wrote on the photo-sharing platform, "It took us 4 Decades and several Provocative photo shoots to open people's minds through ART! It took @stevenmeiselofficial almost as long to join Instagram - just in time to announce our Christie's auction, to benefit @raisingmalawi. Proof that great causes can move mountains.

Last year, Madonna described releasing "SEX" as an "empowering" experience. The chart-topping star also slammed her critics for sex-shaming her at the time.

She wrote on her Instagram Story, "Thirty years ago I published a book called S.E.X. in addition to photos of me naked. There were photos of men kissing men, woman kissing woman, and me kissing everyone. I also wrote about my sexual fantasies and shared my point of view about sexuality in an ironic way. I spent the next few years being interviewed by narrow-minded people who tried to shame me for empowering myself as a woman (sic)."
