First of Two United States Air Mail Forever Stamps to be Dedicated May 1
WASHINGTON — The United States Postal Service will honor the beginning of airmail service by dedicating two United States Air Mail Forever stamps this year.
The first, depicted on the right in blue, commemorates the pioneering spirit of the brave pilots who first flew the mail in the early years of aviation. The first-day-of-issue ceremony will take place May 1, 2018 at 11 a.m. at the Smithsonian National Postal Museum, 2 Massachusetts Ave. N.E., Washington, DC. The event is free and open to the public. Followers of the U.S. Postal Service’s Facebook page can view the ceremony live at facebook.com/USPS. News about the stamps can be shared with the hashtags #AirMailStamps and #USAirMail.
On May 15, 1918, in the midst of World War I, a small group of Army pilots delivered mail along a route that linked Washington, Philadelphia, and New York—initiating the world’s first regularly scheduled airmail service.
The United States Post Office Department, the predecessor to the U.S. Postal Service, took charge of the U.S. Air Mail Service later that summer, operating it from Aug. 12, 1918, through Sept. 1, 1927. Airmail delivery, daily except on Sundays, became part of the fabric 
of the American economy and spurred growth of the nation’s aviation industry.
The second stamp, red and pictured left, will commemorate this milestone with its first-day-of-issue to take place later this summer.
Both stamps, printed in the intaglio print method— a design transferred to paper from an engraved plate — depict the type of plane typically used in the early days of airmail, a Curtiss JN-4H biplane. The biplane was also featured on the stamps originally issued in 1918 to commemorate the beginning of regularly scheduled airmail service. The stamp designs evoke that earlier period.
Background
For airmail service to succeed in the early days of flight, the Post Office had to develop profitable routes, such as between New York and Chicago, and to establish the infrastructure for safely making night flights. It set up lighted airfields and erected hundreds of airmail guide beacons between New York and San Francisco so that by 1924 regularly scheduled, transcontinental flying was possible, day and night.
Airmail delivery, daily except on Sundays, became part of the fabric of the American economy and spurred the growth of the nation’s aviation industry.
The United States Air Mail stamp is being issued as a Forever stamp. This Forever stamp will always be equal in value to the current First Class Mail one ounce price. Stamp design
On the 100th anniversary of the beginning of regular airmail service, this stamp celebrates the courage of the pioneering airmail carriers and the foresight of those who fostered the new service and made it a success. The stamp, printed in intaglio, features a drawing of the type of plane typically used in the early days of airmail, a Curtiss JN4H biplane. This type of biplane was also featured on the 24-cent stamp that was issued in 1918 to commemorate the beginning of regularly scheduled airmail service. The words “UNITED STATES” and “AIR MAIL” are respectively at the top and bottom of the stamp. “EST” is an abbreviation for “established.” The stamp designer and typographer was Dan Gretta; Greg Breeding was the art director.

United States Postal Service Celebrates 100th Anniversary of United States Air Mail Service
WASHINGTON — The U.S. Postal Service celebrates the 100th anniversary of the beginning of regular airmail service with a Forever stamp. This stamp celebrates the courage of the pioneering airmail carriers and the foresight of those who fostered the new service and made it a success.
The first-day-of-issue ceremony for the blue United States Air Mail Forever stamp, took place at the Smithsonian National Postal Museum. Followers of the U.S. Postal Service’s Facebook page can view a video of the ceremony at facebook.com/USPS. News about the stamps can be shared with the hashtags #AirMailStamps and #USAirMail.
“The stamp we’re here to celebrate is a beautiful reminder of the imprint of United States Air Mail on today’s world,” said U.S. Postal Service Vice President of Supply Management Susan Brownell who dedicated the stamps.
Brownell spoke of how this groundbreaking service is credited with establishing the foundation for America’s modern-day aviation industry. “The Wright brothers opened this country’s eyes to what could be possible,” she added. “Fifteen years later, with the first airmail flights, the Post Office helped turn that possibility into reality.”
Joining Brownell to unveil the stamps were Dr. Bill Harris, Deputy Director, Air Force History and Museums Policies and Programs; Elliot Gruber, Director, Smithsonian National Postal Museum; and Nancy Pope, Head Curator, Smithsonian National Postal Museum. (Photo courtesy USPS.)
Harris spoke of the history of aviation, noting the significant contributions of the early pilots. “Challenges would be great,” he said. “But this didn’t dampen the spirits of the pilots who innovated and experimented daily with tactics and landing procedures. After all, what cargo could be more precious than letters to loved ones!”
A second stamp, red and pictured left, will be issued in College Park, MD on Aug.11, 2018. The stamp will commemorate United States Air Mail as an official function of the Post Office Department.
Both stamps, printed in the intaglio print method — a design transferred to paper from an engraved plate — depict the type of plane typically used in the early days of airmail, a Curtiss JN-4H biplane.
