The Twenty-four-cent Prexie
Multiple rates
A letter sent from Hawaii to the mainland for four times the six-cent military concession airmail rate in 1943.
Although this cover specifies that the contents are printed matter, twenty-four cents was sufficient to mail two to three pounds of bound printed matter to zone 8 in 1941. Since it has a first class cancel, it is more likely that it was sent first class and weighed between seven and eight ounces.
