Ralph McQuarrie’s concept artwork was instrumental in helping the Star Wars trilogy find its way to the silver screen. During the production of Star Wars: Episode V - The Empire Strikes Back, set concept drawings like this would later be brought to life in the film. This photostat print of a McQuarrie original showcases multiple views of the ice caves within the rebel base on Hoth. It includes embedded “ok” stamps and production code in the lower left corner.
