The assignment was to create a stamp issuance In honor of the 100th anniversary of the beginning of airmail service. Since there were two important dates to commemorate the design had to work for both occasions--the first to honor the brave Army pilots who initiated airmail service on May 15, 1918; the second to commemorate the beginning of airmail service through the U.S. Post Office Department on August 12, 1918.
The design team decided that a way to honor both dates would be to print the identical stamp in two colors and issue them on two different dates. One of the design elements is a drawing of the type of plane typically used in the early days of airmail, a Curtiss JN-4H biplane. At a distance, the aesthetic resembles the old engraving style, but up close, the illustration and typography take on a refined and modern appearance. The design is complemented by the intaglio printing process for a raised finish.
More than eighty-five percent of the stamps produced in each color have already been sold.
