Crystal scent bottle with Napoleonic portraits

Cut crystal scent bottle with white ceramic paste inlays, with a double portrait of Napoleon and his second wife Marie Louise, later Duchess of Parma. On the back a portrait of their son, the “King of Rome” (1811-1832), based on the Watercolour portrait by Jean-Baptiste Isabey (1767-1855). Hinged silver stopper with hallmarks. Produced in the now lost Cristallerie de Vonêche in southern Belgium, in the province of Namur. This process is erroneously called sulphide glass.
