Someone had the bright idea to invent a reliable receiver that will keep the most important and earliest form of communication in the world – called the a letter or letter box.

Prior to 1850, there are no mailboxes. They appeared after the invention and widespread use of postage stamps, which allow people greater freedom in sending letters via mailbox. With stamps that you no longer need to buy postage from the local post office.

The mailboxes have become a necessity in 1863 when the citizens began to enjoy a free city delivery. Postmen transmit hands letters to people directly to their door without any fees. Although residential mailbox is no longer useful, it was not until 1923, when it became mandatory for every household to have a mailbox, or at least a letter slot.
