A Fine Portrait Miniature of Louis-Philippe (1775-1850), Duke of Orléans, King of the French 1830-1848, facing left, waist-length, in gold-braided blue General's uniform with gold epaulettes and gold sash, decorated with the badges of the Royal French Orders of the Saint-Louis, the Lily and the Legion of Honour, and the three silver breast-stars of the Royal French Order of the Holy Ghost and of the Royal Sicilian Orders of St. Januarius and St. Ferdinand, with black stock, white collar, curly short dark hair and sidewhiskers

Another version of this miniature, signed and dated 1815, formerly in the collection of the sitter's fifth son, the Duke of Aumale, is in the musée Condé, Chantilly, cabinet des gemmes, no. 55.
The gold beater's skin on the reverse of this miniature is inscribed by the artist's hand: 'Augustin A Paris rue Croix des petits Champs no. 25'
H. Bouchot (La miniature française 1750-1825, Paris, 1910, p. 218) relates that Augustin was appointed Cabinet Painter in Ordinary to the King on 15 September 1814, by King Louis XVIII, upon the presentation of three portrait miniatures depicting the King himself, the Duke of Berry and the Duke of Orléans.
