| The “terrible lizards” that once ruled the earth evolved into the public face of the Sinclair Oil Corp. at the 1933 Century of Progress Exposition in Chicago. Asserting that the older your oil fields are, the better your gasoline is, the company dramatized its fuel’s ancient origins in Pennsylvania 270 million years ago with a robotic T. Rex and brontosaurus made of paper mache. The dinos proved so popular a promotion that Sinclair sold rubber versions of them at its stations and trademarked the silhouette of a large green dinosaur, an image that became one of the world’s most iconic corporate logos. |
