In 1854 the Board of the Inland Revenue engaged Jean Francois Joubert de la Ferte to engrave a design of the Queen's head from a drawing by Henry Corbould which was based on the Wyon medal. The 1855 GB 4d stamp was the first to utilise the design. From this master die a number of variants were known as the Diadem Heads. The Diadem IV was adopted as the master for Jamaica.
