A solid gold Darth Vader mask is going on sale in Japan, with a $1.4 million price tag for a one-of-a-kind likeness of science fiction's most famous villain.

Jeweller Ginza Tanaka on Tuesday showcased the 15-kg sculpture, which has been commissioned to mark the 40th anniversary this year of the release of Star Wars. The mask will be available for purchase on May 4 — a date known among fans as ‘Star Wars Day’ because of its similarity to one of the franchise’s most famous lines: “May the Force be with you.”

The jeweller also plans to release gold coins specially designed to celebrate the anniversary in the more affordable price range of $1,200 to $11,000. Ginza Tanaka is celebrating its 125th anniversary this year.
