Design for a Painted Porcelain Plate, Loading or Unloading Goods

Design for a painted porcelain plate, probably for the Service Agronomique. A scene in the courtyard of a vineyard. On a raised platform under a shed roof, four men appear to be pushing an object toward the edge of the platform; in the courtyard, a man carrying a wicker basket on his back is walking away from a cart presumably carrying grapes [?]. A road between two hills winds away into the left distance.
