The bottle appears to relate quite closely to the Guyuexuan group usually found in opaque white glass with enamel painted on the molded areas. For a similar bottle from this group with a blossoming prunus and magpie see Hugh Moss, Victor Graham and Ka Bo Tsang, The Art of the Chinese Snuff Bottle, The J & J Collection, New York, 1993, vol. I, p. 352, no. 204. For a white glass example see Humphrey K. F. Hui and Christopher C. H. Sin, An Imperial Qing Tradition, Hong Kong, 1994, p. 111, no. 135
