Orson Welles' personal manuscripts for Citizen Kane have sold for over $102,000 (£67,187) at auction.
Three screenplays which illustrate the evolution of the classic film were sold by the Profiles In History auction house in California, on Tuesday.
The final revised script was the one "Welles held in his hands while directing the movie, with his camera blocking notes," said the auctioneers.
The seller was a close friend of Welles, who died in 1985.
An original first rough draft of American (the working title for Citizen Kane) sold for $32,000 (£21,100). It was written in 1940 by Welles' collaborator Herman Mankiewicz.
The second draft, described as a fuller evolution of the script, brought in $25,600 (£16,880).
The third and final shooting script surpassed estimations, selling for $44,900 (£29,543). It included Welles' handwritten annotations and directing notes, and was signed by most of the cast principals.
However, it failed to match the $164,000 (£98,500) achieved at Sotheby's last year for Welles' personal copy of the working draft script.
The 229-page document, which contained markings and deletions in pencil and pink crayon, was the subject of a bidding war - having been estimated to fetch about $30,000 (£19,772)
Welles was 25 when he directed and starred in the 1941 film, which tells the story of the rise and fall of a publishing tycoon.
"What's so significant about this is there has been so much written about Citizen Kane that is inaccurate or we just don't know because there are gaps in the story because no one had a source of reference," said Profiles' owner, Joseph Maddalena.
"For people who study film, it's a big deal because you actually now have the entire story."
In addition, a typed manuscript with Welles' handwritten directorial notes for a proposed television adaptation of the movie in the 1950s brought in $20,480 (£13,510).
