These appliques clearly follow a design for a wall-light attributed to Richard de Lalonde circa 1775 which is now in the J. Paul Getty Museum, Malibu (illustrated in G. Wilson and A. Sassoon, Decorative Arts in The J. Paul Getty Museum, 1986, p. 110, fig. 232).

A similar set of six three-light appliques is also in the J. Paul Getty Museum (G. Wilson and A. Sassoon, op. cit., p. 61, fig. 134). A watercolor of prince de Condé's salon at the château de Chantilly shows appliques of this model. It is contained in an album which was presented by the prince to the future Emperor Paul I of Russia and has since been returned to the Musée Condé at Chantilly.
