Approx 12 1/4" X 11"
Lefton? Made in Japan White Green Yellow Orange Pre-owned in Very Nice Condition There are 3 minor chips on the bottom sitting rim...not on the dish itself. Minor crazing on the bottom
I researched this to the best of my ability, but couldn't find this piece. I think it's Lefton or Geo. Z. Lefton... it's only a guess. Anyway you look at it, it's a Beautiful and Interesting Dish.
