I dont know if it is hand painted, not sure what the paint mark is on the top which is in the paint, and the back is plain, no makers mark, Ive seen it with a buffalo mark on the back of other plates but this does not. and not sure if the stand belongs to the plate, just not sure what I have here.. help !
