1934F103.25 Signet Matrix - Seal Matrix Possibly made in Birmingham Presented by Francis Buckley, 1934. A 'signet' or 'seal matrix' is a small stamp used for impressing the mark of its owner in wax onto documents.This is one of a collection of twenty-seven acquired by the museum in 1934. The majority of examples are made of moulded translucent glass. This particular one seems to be a blue paste. The inscription suggests it may have been intended as a love token, as it reads: 'JE VIS EN ESPOIR' ('I live in hope').
