An original Darth Vader Costume from the film Star Wars goes up for bid this month in London and predictions of the winning bid range between $250,000 and $365,000, reports the Associated Press.

According to a Reuters report the auction house said:

“While there are limited public records of the costumes produced and used for the first Star Wars trilogy, the helmet, mask and shoulder armor from the present example have a provenance leading back to the film studios around the time of production.”

Christie’s did not name the owner of the Star Wars memorabilia that will be placed for auction.

However, they added that “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,” reports CBS.
