The Monroe photos -- taken in 1946 when she was still Norma Jean Dougherty -- sold for $352,000.
The photos come with negatives and the rare right to sell and distribute them. A judge in September ruled they must be auctioned to settle debts of photographer Joseph Jasgur.
Other hot items that sold at the Julien's auction included a Lady Gaga dress for more than $31,000 and her prop gun used in his music video for "Born This Way," a 1969 caricature John Lennon drew of himself and Yoko Ono, and a classic Michael Jackson jacket.
