Featuring the profile of Queen Victoria, the One Penny Black, which emerged 177 years ago, was the world's first adhesive postage stamp used in a public postal system. It is undoubtedly a British cultural icon recognized all over the world.
Due to the high complexity of the British postal rates, the adhesive stamp was proposed by Sir Rowland Hill. This Penny Post plan was revolutionary. All mail weighing up to ½ ounce could travel anywhere in the UK for only a penny. The working class could now afford to communicate with those living at a distance.
