In 1934, the 16¢ blue Airmail Special Delivery stamp was issued to prepay, with one stamp, the air postage and the special delivery fee. Mail with this stamp would travel by plane to its designated post office, where, upon arrival, a messenger would deliver it immediately to the recipient.
The stamp was designed by President Franklin D. Roosevelt, who was an avid collector. Its first day of sale was August 30th, at the convention of the American Air Mail Society in Chicago. Two years later, the stamp was reprinted using two colors – carmine and blue – resulting in CE2.
