With the factory mark in blue enclosing the date letter D for 1757, adjacent painters mark of a circle for Jean-Jacques Sioux le jeune (active at Vincennes and Sèvres 1752-60).

This shape of tray with basket sides was called a plateau corbeille and could be square, round, lozange-shaped, triangular, six-lobed or octagonal. They can have pierced or full sides. Early examples were included in the turquoise-blue ground Louis XV service of 1753-55, and they are also found as trays for tea services. The 1977-8 Vincennes exhibition catalogue (p.68) states that the octagonal version first appears in the January 1757 factory inventory, but we know of a 1755 example from the Louis XV service, which, like the factory plaster model, has slightly different raised work on the side.
