Expert opinion is divided over whether they are of Flemish or German manufacture.
Adam de Walsoken, known from his will to have owned a great number of properties in the town, died in 1349 and is shown with his wife Margaret. Below their feet is a rural scene, famous for its depiction of a postmill.
Robert Braunche died in 1364 and is shown with his first and second wives, Letitia and Margaret. He was a merchant and his will implies a riverside property. Below their feet is the famous Peacock Feast scene, which some interpret as an incident in a medieval legend and some as a reference to entertainment provided by Braunche when Mayor to King Edward III.
