Interesting plate or dish, diameter 10 7/8", about one inch deep, with "WADE 333 Calif-U.S.A." on the bottom. I am a fine art dealer so pottery, china and ceramics are not my specialty, but Wade of California it seems was a mid century operation in Southern California---a part of the rich tradition of California pottery. Condition is excellent with no chips. There is a small irregularity in the glaze showing as two tiny white spots adjacent to each other, but this is clearly from the manufacturing process and is not later damage. The bluish colors and patterns in the glazes are very complex. This will look great on any mid century modern teak or rosewood table, for example. See over 3,000 works of fine art in my shop.
