The cup and saucer apparently from the same service is illustrated in the catalogue, fig. 66 and decorated by Vielliard and Levé. The tray of the same pattern in the Wallace Collection has flowers apparently executed by the same hand. As both the Marcus and Wallace Collections' pieces are dated 1757 it is reasonable to assume that the present lot is of the same date. For an extensive discussion of this specific type of decoration, see Rosalind Savill, The Wallace Collection Catalogue of Sèvres pp. 599 - 602.
