Showscan Alien Chevy Commercial Concept Sketch by Ralph McQuarrie

A hand-drawn Ralph McQuarrie alien sketch from the production of a 1987 Chevrolet commercial shot in Showscan. Showscan was a high-speed, large-format filmmaking process pioneered by visual effects master Douglas Trumbull. This advertisement for the Chevrolet Corsica utilized the process to depict a benign abduction by friendly extraterrestrials designed by Trumbull's colleague, Ralph McQuarrie.

This hand-drawn concept sketch for one of the car-obsessed aliens is rendered in graphite on illustration paper, labeled "Showscan Chevy" and "33", and initialed "RMQ" by McQuarrie. It is in excellent overall condition. Dimensions: 11" x 8 1/2" (28 cm x 21.75 cm)
