See Linda H. Roth and Clare Le Corbeiller, French Eighteenth Century Porcelain at the Wadsworth Atheneum, The J. Pierpont Morgan Collection, Wadsworth, 2000, p. 197, no. 93 for a déjeuner tray of the same form dated 1768, and p. 198, fig. 93-1 for a drawing of the shape (without handles) in the Sèvres factory archives. On p. 198 a convincing explanation is given as to why the name plateau 'Duvaux' is incorrect for this model and why plateau 'Duplessis' is more appropriate. The plateau 'Duplessis' was first recorded in 1760 when two were listed among pièces extraordinaires in the factory's inventory. It was produced in two sizes with the second size (of which the present lot is an example) appearing in 1761, when moulds and models were listed at 8 livres each. Two examples ready for glazing in the same year were valued at 15 livres each and undecorated examples at 21 livres. A tray, formerly in the Collection of John Jones, is in the Victoria and Albert Museum, London, museum no. 768-1882, and is also illustrated by William King, Catalogue of the Jones Collection, Part II, Ceramics, Ormolu, Goldsmiths' Work, Enamels, Sculpture, Tapestry, Books, and Prints, London, 1924, pl. 9, no. 119.
