1945 4c Postal Note,black

Unlike regular postage stamps, which are used to pay the rate for mail delivery, postal note stamps together with the postal note cards, were created to send small amounts of money up to ten dollars to anyone on the mainland of the United States. Similar in use to money orders, the stamps were created to send small amounts at a lower cost per transaction than money orders which were cost prohibitive for small values. The stamps were issued from February 1, 1945 until March 31, 1951.
