A Darth Vader mask made of gold will go on sale in Japan next week with a price tag of more than £1 million.

The solid gold mask was commissioned by the upmarket jewellers Ginza Tanaka in Tokyo to mark the 40th anniversary of the release of the film Star Wars.

The 24 karat gold mask - an exact replica of one of Hollywood’s most recognisable science fiction villains - is as heavy as it is pricey, weighing just over 33 pounds.
