The StarWars portfolio by Ralph McQuarrie

Here, McQuarrie developed what was known as the Lash La Rue scene in the depths of the Death Star. The retractable bridge and chasm, over which Luke and the Princess were to swing on a thin cord, were thought to be somewhere close to the center of the battle station. All structures were to radiate from a central core in ever-widening circles.
