The famous picture of Queen Victoria and Prince Albert with their daughter Victoria on her wedding day, 25 January 1858. The Queen is blurry because she couldn't stop shaking from the anxiety of her daughter leaving home.
The world's first postage stamp was issued by Great Britain in 1840. Featuring a bust of Queen Victoria, it has come to be known as the "Penny Black." It also marked the introduction of "uniform penny postage" in a mail system: the rate to carry a letter to ANY destination within the country was now the same, and not based on distance carried.
