(Bloomberg News) Madonna’s conical-bra corset sold for $52,000 at a London auction yesterday.

The Jean Paul Gaultier-designed stage costume was sold moments after a whip used by Harrison Ford, though auctioneer Christie’s International made no connection between the two in a “Pop Culture” auction at its South Kensington salesroom.

Madonna wore Gaultier’s green-and-white corset for the 1990 “Blond Ambition” tour while performing three songs, including “Now I’m Following You.” Its formal estimate was 10,000 pounds ($15,930) to 15,000 pounds at hammer prices and it made 32,450 pounds with fees. It was bought by a bidder in the room, acting for an undisclosed London collector.

Supplies of pop and movie memorabilia have declined in recent years as studios have become aware of their commercial potential, boosting the rarity value of items that do make their way onto the market, said dealers.

A black Lycra two-piece labeled “Trashy” that Madonna wore to perform “Vogue” had an upper estimate of 12,000 pounds and fetched 16,250 pounds.

The hand-made 12-plait kangaroo-hide bullwhip produced for one of the Indiana Jones movies was also estimated at 10,000 pounds to 15,000 pounds. It sold for 20,000 pounds ($32,000) to an Internet buyer.

It was one of more than 30 props produced by whipmaker David Morgan and featured in the “Temple of Doom” film in 1984. The whip was first donated by Steven Spielberg to a Unicef charity auction in 2001, when it was sold for 68,000 pounds, Christie’s said.

“Indiana Jones is a timeless classic,” said Tim Lawes, general manager of the dealership, The Prop Store of London. “That was the cheapest whip with a provenance I’ve seen, though. They have made $40,000 to $50,000 before.”

Lawes paid 18,750 pounds for the ’Grail Diary’ prop from the 1989 movie “Indiana Jones and the Last Crusade.”

Lawes said film memorabilia was now attracting alternative investors, particularly for Bond, Star Wars, Indiana Jones and Spielberg films.
