The World's Fair in St. Louis opened 100 years ago today (Friday).
The Missouri History Museum is marking the anniversary with a new exhibit that will open Sunday, May 2.
More than 250 artifacts that were sold, used or shown at the fair will be on display.
KWMU's Tom Weber prepared this preview of the exhibit, which is called "Looking Back at Looking Forward."
