A 17-inch model of Doctor Who's Tardis, first used in a 1965 episode of the classic BBC science fiction series, has been sold for £10,800.
Tardis stands for Time and Relative Dimension in Space
The plywood time-travelling device, built at the BBC visual effects department, was sold at Christie's auction house.
Christie's said one of its last screen appearances as a prop was in 1970.
Two stormtrooper helmets from Star Wars sold for £19,200 and £18,000 in the entertainment memorabilia sale.
Sarah Hodgson, head of popular entertainment at Christie's said: "There was strong international interest throughout today's successful sale for film and entertainment memorabilia from all eras.
"The Stormtrooper helmets from Star Wars and the Tardis from Doctor Who performed particularly well and attracted strong prices, with all doubling their pre-sale estimates."
The two Imperial Stormtrooper helmets featured in the 1997 film Star Wars: A New Hope.
The Stormtrooper helmets were rescued from a film studios skip
All 12 used during the desert sequence shoot were thrown away but two were later recovered from a skip at Elstree studios.
Both items had been estimated to fetch £8,000 to £10,000.
Props from Harry Potter and the Philosopher's Stone, including a Hogwarts school gown had been due to go on sale, but there was a last-minute dispute over ownership.
However, a wand from the film went for £3,120, way above its estimate of £300-£500.
