The Thirty-cent Prexie
Midway Island use
The airmail rate between Midway Island and the US mainland from sometime around late 1940 until December 25, 1941 for military personnel and October 23, 1942 for civilians employees and contractors was thirty cents per half ounce.
A cover sent from Midway in 1941 by a member of Battery "I", 3rd Defense Battalion of the Fleet Marine Force.
This cover was sent by a civilian on Midway in August, presumably 1941 as it is not censored. The year date is unreadable.
