The Pan- American Union Building of Washington, D.C., was selected as the design for an airmail stamp issued primarily for use on airmail material destined for Central and South America.
The Pan-American Union was formed in 1910 as a means for its members, the United States and the countries of Latin America, to exchange information and discuss matters of common interest. In 1948, it became the Organization of American States.
