Very heavy very large studio pottery tray I believe possibly for bonsai or Japanese style tree crafts- I don’t know anything about it but that is based on the estate in which it came. It is marked but I can’t identify the maker. The quality and it being entirely handcrafted immediately caught my attention- this is a very nice piece. Measures 10.25” x 15.5” by 2.5” tall. No damage. Very very light wear inside where it appears maybe a few small pots were inside. Very difficult to see.
