Research on these plates brings up no potential time frame for production. Due to the lack of information, the work was most likely commissioned. Superb quality. Obviously high end production in both the art work and the construction of the plates. SET OF FIVE PLATES Individually hand painted English Ivy rimmed dinner plates with 22K gold trim. The mark is Atlas China New York. The signature on the artist is hard to determine. I get WALNK. However, that makes no sense. Excellent unused condition. Paint content unknown. No chips no cracks no breaks These are about 10 1/2" wide. We will combine shipping as much as possible for multiple items.
