Recorded at Sèvres as a painter specializing in Chinoiseries, arabesques, and butterflies and as a gilder, 1761-1764, 1772-1800, Louis-François L'Ecot was arguably the most gifted of the only two or three artists capable of executing the delicate Chinoiserie decoration found on the present vase.

Préaud,"Sèvres, la Chine et les "chinoiseries" au XVIIIe siècle", Journal of the Walters Art Gallery, Baltimore, no. 47, 1989, pp. 39-50 for a detailed discussion of chinoiserie decoration at Sèvres and a listing of known déjeuners with such decoration.
