A rare pair of Chelsea-Derby club-shaped toilet bottles and stoppers circa 1760-70

decorated on either side with a raised oval pale yellow-ground panel depicting a female or male portrait medallion painted en grisaille, suspending from a ribbon, applied with satyr's masks scroll handles and raised on a tall quatrefoil base applied with ram's heads.

The bottles are in generally good condition apart from very minor wear to the gilding in places. The stoppers are soft to the touch and have some minor overspray; which is not very apparent and the exact cause of any possibly damage cannot be determined.
