Today we're going to discuss the history of the postal service. In the 19th century, the introduction of the postage stamp revolutionized communication. Before stamps, the recipient, not the sender, paid for the delivery, which often led to refused letters. The first adhesive stamp, the Penny Black, was issued in Britain in 1840. It featured a portrait of Queen Victoria and cost one penny. Interestingly, despite its name, the stamp was actually printed in black ink, but the design was so intricate that it was difficult to forge. This innovation quickly spread to other countries, and by the 1850s, many nations had adopted similar systems.
