A contract signed by John Steinbeck handing over rights to The Grapes of Wrath to 20th Century Fox has fetched $24,000 (£12,250) at a charity auction.
John Steinbeck received the Nobel Prize for Literature in 1962.
A selection of other Hollywood memorabilia fetched a total of $267,280 (£136,562).
The collection included letters and contracts signed by Marilyn Monroe, Humphrey Bogart and Audrey Hepburn.
The money is going to the Motion Picture and Television Fund, a charity supporting the Hollywood community.
The Steinbeck contract had been expected to sell for up to $6,000 (£3,000).
The letter signed by Marilyn Monroe in 1947, shortly after she changed her name from Norma Jean Baker, went for $7,000 (£3,5000), which was within the estimated price range.
Funds from the auction were earmarked for health insurance for those supported by the Motion Picture and Television Fund.
