The Discovery Channel Online offers a retrospective of the 1939 World's Fair, whose theme was "The World of Tomorrow." The transportation section includes pictures of "Futurama" -- the General Motors exhibit, not the Matt Groening cartoon show.

The site bills Expo 2005 as "a laboratory for the technologies and lifestyles that will be needed for the new millennium." But unlike the 1939 event, where General Motors revealed its vision for a paved planet, the fair will show how people can live in harmony with the environment.
