Louisiana Purchase Exposition & Stamps
On April 30, 1904, the Louisiana Purchase Exposition opened to the public. That same day a set of five stamps commemorating the exposition and the purchase went on sale.
Also known as the St. Louis World’s Fair, this expo was held from April 30 to December 1 and commemorated the 100th anniversary of Thomas Jefferson’s Louisiana Purchase. The largest fair up to that time, it had over 1,500 buildings and 75 miles of roads and walkways. The fair’s opening ceremonies were presided over by President Theodore Roosevelt and Secretary of War William Howard Taft.
