From Steven: A deep bowl, interior gilt on white, exterior green, red and gilt, unusual cartouche type seal
Yinchun - The seal has two Chinese characters. First rotate the picture counterclockwise 90 degree,then read up to down: first character is "Tao", means pottery; second one is "le", means enjoyment here. I guess the potter may be Chinese ,japanese or Korean
Steven - Thankyou, Yinchun, I am very grateful to know that. The origin of this pot has been a great puzzle to me, and it is most satisfying to have some genuine information about it!
