In 1938, Pennzoil made its case for motor oil quality by pointing to the sky — a gleaming United Airlines propeller plane, a well-dressed family boarding, and a tagline that dared you to think: "What Oil Would You Want in This Plane?" Printed in two colors, yellow and black, the graphic impact is immediate and timeless. The reverse carries quarter-page ads for Walk-Over shoes and GEMEX bracelets.
