From May 15-31, 1938 Postmaster General James A. Farley and he nation celebrated the twentieth anniversary of the first airmail flights with National Airmail Week. Congratulatory messages poured in to postal headquarters from all over the country, all of them flown by air. National Air Mail Week was intended to demonstrate that the service was no longer experimental, but had instead become the backbone of the American mail system.
