1934F103.3 Signet Matrix - Seal Matrix, 1750-1850 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 finely made of moulded translucent glass, in this case mauve. Several bear engraved inscriptions in reverse, as in the case of this example which has a design of a tree and reads: 'WITHOUT THY SUPPORT I DIE'
