Lot Essay
The fashion for replacing the bottom of porcelain cups with sulphide portraits set between glass discs reached its height during the Restoration. It is known that specific glass manufacturers supplied the portrait 'sandwiches' to specific porcelain manufacturers. In the present lot, the male portrait was supplied by Nicolas Despréz to Darte Frères. The female portrait, although inset into a cup of the same form, was likely supplied by a different glass manufacturer, as the rim of the discs are not beveled and the font used to impress the factory mark or sitter's name varies, as does the quality of the modeling.
