Jean DUPLESSIS-BERTAUX (1747-1818) Set of three military engravings, monogrammed "f(ecit) D. B.", depicting officers in uniform during the Napoleonic Empire. - Capitaine de Dragons: A light cavalry officer, recognizable by his ornate uniform and plume, leading his troops on the battlefield. - Officier d'Honneur du Palais: Prestigious figure representing an officer assigned to the ceremonial and protective services within imperial palaces, illustrating the link between the army and imperial power. - Lieutenant d'Infanterie Légère: Soldier on the move, saber raised, embodying the discipline and dynamism of light infantry troops, essential to Napoleonic campaigns. The backgrounds of each engraving depict military scenes, including horsemen in action and soldiers in formation, reinforcing the realism and visual impact of these illustrations. Each engraving is numbered, and was probably part of a suite of engravings on a military theme. The inscription "Duplessis Berthault" in pencil can be found at top left, attesting to the collection from which these engravings come. Engravings cut out and mounted on a cardboard support with visible annotations, in good condition.
