The outfit — a jet-black helmet, mask and armor — was expected to sell for between 160,000 pounds and 230,000 pounds ($250,000 to $365,000). The reserve price is confidential but generally it is just under the minimum expected price.

Christie’s said bidding stopped at 150,000 pounds.

The costume is thought to have been made for “The Empire Strikes Back,” the second film in George Lucas’s sci-fi series, released in 1980.

The auction house’s head of popular culture, Neil Roberts, said the costume is one of the most iconic in the history of cinema.

Christie’s did not name the seller, identified only as an American private collector.
