Part of a script for Orson Welles' film classic Citizen Kane has smashed its pre-auction estimate of $2,000 (£1,250) after going under the hammer for $15,000 (£9,375).

Two dozen pages of the 1941 screenplay went up for grabs on Saturday (26Apr14) as part of a treasure trove of memorabilia offloaded by the filmmaker's youngest daughter Beatrice and handed to bosses at America's Heritage Auctions.

Another highlight of the event was Welles' old Bell & Howard camera, which he had used to shoot footage of a bullfight in Spain. That sold for $37,500 (£23,438).

A silver-plated ashtray, which was gifted to the director by Ernest Hemingway, was also a big bidding hit, going under the hammer for $5,000 (£3,125).

All 67 lots auctioned, fetched a total of $180,000 (£112,500).
