Bikini-clad photos that the actress posed for — when she was only 15! — and which were taken by photographer Harry Langdon, are now for sale on the auction Web site profilesinhistory.com.

Auction cataloger Ryan Dohm tells HollywoodLife.com EXCLUSIVELY, “The photos are unusual in the fact that she is young and Langdon shot her at a young age. They are stunningly done.”

In the photos, Angelina is wearing a bikini, on all fours, and has wet hair. Other photos of Angie are headshots, but the two very racy ones, taken in black and white, are up for auction, with bidding starting at $400-$600.

Profiles in History, the Calabasas, CA auction house which is selling the photographs, says they are “the world’s largest auctioneer of original Hollywood memorabilia.”
