Every stamp of the Louisiana Purchase Exposition Issue portrays a person except the last, which features the very subject the Exposition actually celebrated—the lands of the purchase. The 10-cent stamp features a map of the United States with an outline of the new Louisiana Territory, a very fitting cap on a set of beautiful commemoratives.
The 10-cent stamps most often paid the domestic registered mail fee plus the domestic first class rate or double the UPU rate. Patrons also used it with other denominations to fulfill large weight and destination rates. The Bureau of Engraving and Printing produced 4,011,200 of these stamps.
