Own the Complete 1946-47 Airmail
Rotary Press Printing Set
In August of 1946, President Harry S. Truman signed an Act of Congress that reduced the domestic airmail rate from 8¢ per ounce to 5¢ per ounce, creating the need for new stamps. Among these was the 5¢ DC-4 Skymaster. This stamp was issued to replace the previous airmail stamp. The post office wanted to provide a stamp in a size more suitable for coils, stamp vending machines and booklets of stamps.
Also issued to meet the new rate was a 10¢ stamp picturing the Pan-American Union Building of Washington, D.C. These stamps were generally used on mail destined for Central and South America.
The 15¢ Statue of Liberty stamp was issued primarily for use on airmail material destined for Europe and parts of North Africa. The subject of the design, the Statue of Liberty and the City of New York, was selected because New York was the major port of entry from these countries.
Additionally, the 25¢ San Francisco-Oakland Bay Bridge stamp was mostly used on airmail destined for the Pacific and certain African and Asiatic areas. Most immigrants and travelers from these regions entered the U.S. under the San Francisco-Oakland Bay Bridge.
