The original Batmobile from the 1960s television series has sold at a US auction for $4.2m (€3.15m).
A spokeswoman for the Barrett-Jackson Auction Co in Scottsdale, Arizona, says the winning bidder had not been disclosed.
The 19ft black, bubble-topped car was used in the Batman TV show that starred Adam West as the Caped Crusader.
The car’s owner – famed customiser George Barris, of Los Angeles – transformed a one-of-a-kind 1955 Lincoln Futura concept car into the sleek crime-fighting machine.
On the show, it boasted lasers, a “Batphone” and could lay down smoke screens and oil slicks.
Mr Barris’ publicist said his client was pleased with the auction result.
