Great Britain commemorative stamps 1980–1989
The United Kingdom, known in philatelic circles as Great Britain, released many commemorative stamps (postage stamps issued to honour or commemorate a place, event or person) in the 1980s. History. Postage stamps were first issued in the United Kingdom on 6 May 1840, with the introduction of the world's first adhesive postage stamp, known as the Penny Black. Until 1924, all British stamps depicted only the portrait of the reigning monarch, with the exception of the "high value" stamps (also known as the "Sea Horses" design) issued in 1913, which were twice the size  of normal stamps with added pictorial design. In 1924, the first "commemorative" stamp was issued for the British Empire Exhibition. There were then occasional issues over the next thirty years, when the frequency of new issues became more regular. From the mid-1960s, in most years, six to nine sets of commemorative stamps have been issued every year. PHQ cards, postcard-sized reproductions of commemorative stamps, have also been issued to accompany every new set of stamps since the mid-1970s.
