The rare example of 16th century East Anglian silver carries Norwich assay marks for 1567 (just two years after the first Norwich hallmarks appeared) and a flatfish or butt that is a pun on the name of the maker Thomas Buttell (fl. c.1564-after 1570).
The inscription to the cup reads
For The Tovn of Ryps and Bastwyc.
