Designs (2 on 1 sheet) for a small mantel clock, which is a clock designed to rest on mantels above fireplaces, usually squat, heavy and lacking handles. The design shows the front of the mantel clock and a disk, decorated with two female portrait heads, probably for the back and at full scale (diameter 9.5 cms). They were drawn by an anonymous designer about 1785, possibly for an elite client of the Court of Louis XVI, King of France from 1774 until 1791, at Versailles, Paris.

The designs are from an album of designs which date from about 1735-1820 and includes those for snuffboxes, scent holders, watches and watch cases, spoons, fans and fan mounts, small swords, and chatelaines (ornamental chains, pins, or clasps usually worn at a woman's waist, to which trinkets, keys, purses, or other articles are attached).

There is a close relationship between the contents of the album and known work by three Parisian goldsmiths, Jean Ducrollay (1710-1787), Pierre- François Drais (active 1761-1788), and Charles Ouizille (1744-1830) whose names appear on the first page of the album. This suggests that all the designs emanate from their workshops. Drais worked for the Court at Versailles as jeweller to both King Louis XV and Louis XVI. Ouizille worked in this capacity for Louis XVI. Most of the material dates from the period 1755-90.
