Isabey had his own room in the château where he produced views of the interior in 1815. After the death of Claude Caroillon Destillières in 1814 the Château de Pontchartrain passed to his daughter Aimée who in 1817 was married to Charles-Eustache-Gabriel, known as Rainulphe Eustache d'Osmond. Rainulphe Eustache was the brother of Adèle d'Osmond, countess of Boigne, whose portrait Isabey also painted. Isabey created the "Portrait d'Eustachine-Jeanne D'Osmond" (1828), the daughter of Aimée, born in 1827. Isabey portrayed many aristocrats, including a "Portrait of the countess Maria Walewska", and sovereigns. His portrait of "Napoleon at Malmaison" (1802) was praised for its excellent likeness to the emperor. During the years of 1830-48 Isabey directed the artists’ studio at the Sèvres porcelain factory. - Traces of old folds..
