Louisiana Purchase ExpositionThe Louisiana Purchase Exposition, informally known as The Saint Louis World's Fair, was a World's Fair held in Saint Louis, Missouri in 1904 which celebrated the centennial of the Louisiana Purchase (delayed one year). It opened April 30, 1904, and closed December 1 the same year. The Fair Grounds covered 1,200 acres, the largest space of any fair, and it was probably the most grand of the old style Pre-World War I Fairs. There were over 1500 individual buildings, connected by some 75 miles of roads and walkways, and it was said to be impossible to give even a hurried glance at everything there in less than a week. Exhibits were staged by 62 foreign nations, the United States government, 43 of the American states, in addition to the numerous exhibits put on by many industries, cities, private organizations and corporations, theater troops, music schools, etc.
