Batman's batsuit is expected to sell for £60,000 ($110,000) at a rare film and television memorabilia sale in the UK.
The costume, which featured in 2012 hit The Dark Knight Rises, will be sold alongside Batman's Batpod motorcycle and more than 500 original items from other films at an auction next month.
Keira Knightley's wedding dress from Love Actually is expected to sell for between £5000 to £7000, while the Sloth Mask from 1985 film The Goonies could reach £40,000.
The auction, held by Prop Store, will be England's largest live sale of film and television memorabilia with lots expected to sell for more than £1.5m in total.
Other items include Arnold Schwarzenegger's original Terminator 2 Judgment Day costume, Harry Potter's Hogwarts acceptance letter, and Spielberg's clapperboard from Jaws. The lots will be on display at the BFI IMAX in London from September 14 until the auction on September 27.
Stephen Lane, Prop Store chief executive, said the sale was "truly unique event".
