The world’s first postage stamp

Britain’s Penny Black is considered the world’s first adhesive postage stamp. It dates back to May 1, 1840. Back in those days postage was charged based on the number of sheets being posted and on the distance the letter had to travel. Not much has changed today. Our postal rates are based on distance as well, and on weight (as opposed to the number of sheets). And notice that the tradition of using a monarch’s portrait in profile is another thing that hasn’t changed much.
