18th Century Delft Trefoil Hinged Lid Trinket Box - Adriaen Pynacker Design.An 18th century Delft trinket box, of trefoil form, with hinged lid. The box is unsigned, however the design is an Adriaen Pynacker delft design. The trinket box is in a very good condition. There is one small 'C' shape hairline crack to the front left of the lid, however this is barely visible and does not affect the design of the piece (please see photographs). The hinged lid operates with ease and the front clasp clicks shut as it should when
