At the Chicago World's Fair of 1933–1934, included in the Century Of Progress exposition, Sinclair Oil Refining sponsored a dinosaur exhibit meant to play on the link between the formation of petroleum deposits and the time of dinosaurs. The exhibit included a 2-ton animated model of a Brontosaurus. The exhibit proved so popular it inspired a promotional line of rubber brontosaurs at Sinclair stations, complete with wiggling heads and tails, and the eventual inclusion of the Sinclair brontosaur logo. Later, inflatable dinosaurs were given as promotional items. An anthropomorphic version appeared as a service-station attendant in advertisements. Some locations have a life-size model of the mascot straddling the building's entrance. (wiki)
