This large stoneware round serving platter chop plate is in Mikasa's Whole Wheat pattern E8000 from the 1970s. Undecaled, it will mix and match perfectly with any of the decaled Whole Wheat series like Jardiniere, Granola, Wild Rose, Autumn Song, and several others.
The platter measures 12-3/4 inches diameter. It's in absolutely perfect condition with no wear or damage at all. The glaze in completely intact with no utensil or even stacking marks. I doubt it was ever used.
