Plate, probably Staffordshire, England, ca. 1765–1770. White salt-glazed stoneware. D. 9 1/4". (Copyright, The Fitzwilliam Museum, Cambridge.) While commemorative salt-glazed dishes with molded inscriptions for “The King of Prussia” and “William Pitt” are well known and were produced in large quantities, the “Bartholomew Fuller” plate is the only known example of a previously undocumented custom order for Trinity College.
