Penny Black

Where was the first stamp introduced in the postal system?

     In Britain, during the Victorian Age.

The Penny Black was the world's first adhesive postage stamp used in a public postal system. It was issued in Britain on 1 May 1840, for official use from 6 May of that year and features a profile of the Queen Victoria.The idea of an adhesive stamp to indicate pre-payment of postage was part of Sir Rowland Hill's 1837 proposals to reform the British postal system; it was normal then for the recipient to pay postage on delivery
