Pierre AUDOUIN (1768-1822). Draughtsman, engraver. Portraits of Emperor Napoleon and Empress Josephine. Paris, Chez Pierre Audouin, Circa 1805. Pair of engravings published by Audouin, including: - The portrait of Emperor Napoleon after Charles de Chatillon, with vignette depicting the Battle of Austerlitz, after Duplessis-Bertaux and engraved by Bovinet. 49 x 21 cm (at sight). Fair condition, scattered stains. - Portrait of Empress Josephine with vignette depicting the 1804 coronation, after Jean-Antoine Laurent Laurent and engraved by Lerouge and Bovinet. 49 x 21 cm (at sight). Small scattered stains. Anecdote: A few years later, when Napoleon married Marie-Louise in 1810, Audouin republished the portrait of the Emperor he had published in 1806, and wishing to match it with that of the new Empress, dispensed with a plate. Although the publisher used Josephine's portrait to create that of Marie-Louise, he omitted to change the bas-relief of the first empress's coronation. He commissioned a second proof of this plate, deleting the cartouche and replacing it with a centered inscription of the double-headed Austrian eagle, and modifying the legend and dedications. Engravings framed under glass.
