For a similar Daoguang-marked bottle with identical scenes, but lacking the mask handles found on the present example, see Xia Gengqi and Zhang Rong (ed.), Masterpieces of Snuff Bottles in the Palace Museum, Beijing, 1995, p. 162, no. 165. Also see Moss, Graham, Tsang, A Treasury of Chinese Snuff Bottles, The Mary and George Bloch Collection, Hong Kong, Volume 6, Part 3, p. 708, no. 1325, for an example that is very similar to the present bottle, along with a discussion of the symbolism.
