The Twenty-cent Prexie
Airmail to and from Hawaii
Airmail between the U.S. mainland and Hawaii cost twenty cents for the first half-ounce between April 21, 1937 until January 15, 1945.
A cover sent airmail to the island of Kauai in 1944.
This cover was mailed from Honolulu on December 17, 1941, ten days after the bombing. From evidence of registered letters sent on the eighteenth and nineteenth of December, it probably did not reach the mainland until January 3, 1942.
