Ralph McQuarrie was a cornerstone of the Star Wars universe, creating some of the sci-fi franchise's most iconic concept designs, including Darth Vader's look. He applied his unique vision to the Star Trek universe in 1976 and helped create an unusual version of the USS Enterprise, which is now going up for auction.

McQuarrie worked with legendary set designer Ken Adam, known for his work on James Bond films, to create concepts for Star Trek: Planet of the Titans, a 1976 Trek revival film that was never produced. That collaboration resulted in a 15-inch-long (38 centimeters) model based on their Enterprise design.
