Trois mâts au port The drawing on display is the preparatory study for the painting "Volier à Rouen", an oil on canvas piece currently at the Musée Faure in Aix le Bain, France. The drawing and the painting are entirely similar: one sees in both the same sailboat silhouetted and the boats in the same position, as well as the surrounding landscape in which the bridge in the background is recognizable.
