The present miniature appears to derive from an ivory miniature by Jean-Baptiste-Jacques Augustin, signed and dated June 1814, sold Christie's, London, 15 October 1996, lot 163. Another version, dated 1815, exists as well as a signed copy by Jean-François Hollier, a portrait painter at the Sèvres manufacture. They are described and illustrated in colour in N. Garnier-Pelle, Les Miniatures du musée Condé à Chantilly. Portraits des maisons royales et impériales de France et d'Europe, Paris, 2007, p. 126.
