See Robert D. Aronson assisted by Suzanne M.R. Lambooy, Dutch Delftware, including Selections from a Distinguished Manhattan Collector, Amsterdam, 2009, p. 69, no. 43 for a dish commemorating the Dutch royal family dated 1749, the format of the portrait, the positioning of the title and date within a shaped reserve, and the border decoration identical to that on the present example.
Dated 1748, the present dish will have been made to honor William Augustus, Duke of Cumberland (1721-1765) and the younger son of King George II of England. As general for the English forces, Cumberland was instrumental in ending The War of the Austrian Succession which for eight years had pitted Austria and her allies England and the Dutch Republic against France and Prussia. A treaty was signed at Aix-La-Chappelle or Aachen on 18 October of that year.
