Glass black Yangzhou overlay
Glass, single overlay of brownish-black on an opaque white ground, carved in low relief with a deer reclining beneath a pine, lingzhi fungus, and a bat, below a seal (Ziwan); the other side with a cat chasing two butterflies fluttering near chrysanthemums. The inscription reads :Bi de qi shou 必得其壽 ‘[The person with superior virtue] will assuredly attain the long life to which he is entitled]’. A phrase originating in the Zhong yong.
