Thursday's sale of the topless photo of Bruni by photographer Michel Comte sparked a bidding war among potential buyers, the New York Daily News reported.
"There was a protracted bidding battle on the phone, on the Internet and in the room," said Rik Pike of Christie's.
A bare-chested photo of Bundchen drew a top bid of $193,000, while a portrait of Bardot by Richard Avedon sold for $181,000.
The 135 photos were from a collection of Gert Elfering, who had bought up iconic images of gorgeous women, especially in their birthday suits, the Daily News said.
