The Diana shapes was introduced by the Edwin M. Knowles China Company in 1933. It must have been produced for a very short time since very little of it is found today. The advert to the right is a copy from a 1933 trade journal. It shows one of many lattice work decals that were applied to the open panels of the shape.
The advertisement reads: "Diana. A new shape of modern lines, yet it holds that tough of quaintness which adds charm and grace to the table and receives the admiration of every woman. The quaint panel effect suggests many interesting decorations. Samples mailed on request."
Most Diana will be found marked with the standard Knowles backstamp and date code.
