Sinclair Dinosaur Exhibit
The Dinosaur Exhibit built by the Sinclair
Refining Company at the 1933 World's Fair in
Chicago is the first attempt to recreate out-of-
doors a portion of the earth's surface as it
existed 100 million years ago. The huge beast
shown on this card is a Brontosaurus. He
bulked 40 tons in life and was 70 feet long.
