Jean DUPLESSIS-BERTAUX (1747-1818) Set of three military engravings, monogrammed "f(ecit) D. B.", depicting emblematic figures of Napoleon's Imperial Guard. - Major du Régiment de Ligne: Senior officer of a line infantry regiment, dressed in a richly decorated uniform, symbolizing his rank and authority. - Grenadier à cheval de la Garde Impériale: Elite cavalry soldier, belonging to the prestigious Imperial Guard units. - Chef d'Escadron des Hussards: Light cavalry officer commanding a squadron of hussars, a unit famous for its speed and daring on the battlefield. Each scene is illustrated with a background showing troop movements and artillery in action, adding striking military realism. Each engraving is numbered and was probably part of a suite of engravings on a military theme. The signature "Duplessis Berthault" in pencil is at top left, attesting to the collection from which these engravings came. Engravings cut out and mounted on a cardboard support with visible annotations, in good condition.
