Technical Observations: The patina is black with areas of green and red. The black areas of the surface are well preserved. There are bright scratch marks from cleaning. Wear on the hinge loops on the back appears to be the result of original use of the object.
The object is a solid cast, and the hinge elements are integral to the casting. The relatively flat shape of the back of the head suggests the wax model for the head was cast in a mold. The hinge projections on the back and the cylindrical element on the bottom could have been added by directly attaching additional elements of wax. The details of the face were made using a small punch tool after casting.
