The tiny profile portrait of Washington was produced by Charles Balthazar Julien Fevret de Saint- Mémin (1770-1852) and was specifically made for Washington mourning rings. The engraving was based on a sketch by Saint-Mémin in late 1798 and it is thought to be the last portrait of Washington drawn from life. In order to produce the miniature portrait the artist used an instrument known as a physiognotrace.
