On July 1, National U.S. Postage Stamp Day recognizes
the ease and simplicity with which we can send and receive mail.
A stamp represents payment for the delivery of a letter or a package.
The United States issued its first postage stamp on July 1, 1847.
At that time, stamps were not required.
A letter could be mailed without a stamp and delivery paid for by the recipient.
In 1855, the postage stamp became mandatory.
