Jean DUPLESSIS-BERTAUX (1747-1818) Set of three military engravings, monogrammed "f(ecit) D. B.", depicting emblematic figures of Napoleon's Imperial Guard. - Chasseur à pied de la Garde Impériale: Soldier in regulation uniform, recognizable by his high, furry cap and bayoneted rifle. They were the Guard's elite infantry, renowned for their endurance and discipline. - Sapeur de la Garde: An imposing figure with a distinctive apron and an axe slung over his shoulder, characteristic of the sapper units whose mission was to open passages, build bridges and clear obstacles in battle. - Maréchal des Logis des Chasseurs de la Garde: Cavalry officer, equipped with his saber and richly decorated uniform, supervising the movements of his troops. His role was essential in coordinating and supervising the Guard's mounted units. Each scene is illustrated with a background showing troop movements and artillery in action, adding a striking military realism. Each engraving is numbered and was probably part of a suite of engravings on a military theme. The inscription "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.
