It is unusual to find boxes that are decorated on both top and bottom surfaces, although there are several known examples, such as the slightly larger box included in the exhibition 2000 Years of Chinese Lacquer, Oriental Ceramic Society of Hong Kong and The Chinese University of Hong Kong, 1993, illustrated in the Catalogue, no. 70. As on the present lot, the exhibited example is heavy for its size and it is highly likely that these boxes are constructed with metal cores.
