This round plaque is from the 18th century and is likely from the Qianlong period. There is amazing miniscule detail of this landscape scene. There is rippling of the glaze as well as pig bristle holes in the glaze which is typical of the period. It measures 9.75 inches in diameter. The wood backing of the plaque has been replaced. I have more photos available on request. I consider this plaque to be in excellent antique conditon.
