"He was about to turn it in (to Random House) and he was inspired to change that name," Livingston said.
Livingston said the auction was not timed to a new Broadway adaption of "Breakfast at Tiffany's" now playing at New York City's Cort Theater, saying that was just "serendipitous."
Capote — in creating his Holly Golightly character — is said to have found inspiration in his close friendships with designer Gloria Vanderbilt and Oona O'Neill, daughter of playwright Eugene O'Neill.
"Breakfast at Tiffany's" was not Capote's debut. He had received critical acclaim for his novel "Other Voices, Other Rooms," a decade earlier.
But when "Breakfast at Tiffany's" was published, Norman Mailer wrote that he didn't know Capote well but thought of him as "the most perfect writer of my generation. ... I would not have changed two words in 'Breakfast at Tiffany's.'"
