The Yeoman of the Guard small prototype character jug modeled by Stanley J. Taylor and produced by Royal Doulton of Burslem, England, in 1990. Under its official title, "The Queen's Body Guard of the Yeomen of the Guard," this is the oldest extant British military corps. Created by Henry VII in 1485 at the Battle of Bosworth Field, it is a permanent corps in attendance on the sovereign of England, a part of the royal household, whose duties, now purely ceremonial, were originally that of the Sovereign's personal bodyguard. The Yeomen of the Guard accompany the Sovereign at the annual Royal Maundy Service, investitures and summer Garden Parties at Buckingham Palace, among other events. However, their most famous duty is to search the cellars of the Palace of Westminster prior to the State Opening of Parliament, a tradition that dates back to the Gunpowder Plot of 1605, when Guy Fawkes attempted to blow up Parliament. A raven and tree trunk form the handle of the jug.
