It seems that this model of bottle can be found with varying degrees of success in the painting. They, therefore, must have been workshop production pieces with artists ranging in skills. For another example with less fine details, see Sotheby's Hong Kong, Fine Chinese Snuff Bottles from the Collection of Arthur Gadsby, May 2, 1991, lot 130

For another with less fine face but finer details to the robes, see Robert W.L. Kleiner, Chinese Snuff Bottles from the Collection of John Ault, fig. 136; and another see Bob C. Stevens, The Collectors Book of Snuff Bottles, no. 317
