Stamps are authorized impressions or marks used for the prepayment of a tax or fee. It is an official mark or seal indicating an approval, ownership, or payment of tax. The history of stamps can be traced back to the sixteenth century. The first official royal mail office was opened in England in 1516. Later, mail was required to be paid for by the recipient rather than the sender; this system proved too problematic for everyone because of the resulting preponderance of undelivered mail. The concept of adhesive postage stamp was introduced by James Chalmers in Great Britain in 1834. Brazil issued stamps in 1843, and in the United States, the adhesive postage stamp was officially issued in 1847.
