Edward Weeks (1866-1960) was a letter and frame engraver working for the Bureau of Engraving and Printing. His most ‘famous’ work was that on the 1918 airmail stamps issued in the United States.
Weeks worked over thirty hours spread out over two days on the frame and lettering of those airmail stamps. While it was always thought that Marcus Baldwin engraved the vignette, an entry in the BEP records showed that Weeks spent just over two hours working on the vignette as well, after Baldwin had finished it. This seemed to be corroborated by an entry in Baldwin’s diary, reading “Mr. Weeks did the lettering”. Although for a long time, this was thought to refer to the frame and lettering engraving of Weeks, the two facts together proved that it was indeed Weeks who finished the engraving of the vignette by adding the serial number 38262 of the plane. This number had only been made public after Baldwin had finished his work. As luck would have it, out of the six new planes, it was the one carrying this serial number which was the first to fly ceremoniously from Washington DC.
