For a very similar bottle with a pale blue monochrome glaze signed by Wang Bingrong see Robert W.L. Kleiner, Chinese Snuff Bottles from the Collection of Mary and George Bloch, Hong Kong, 1987, col. pl. 236. The author states that a number of private kilns were in production at Jingdezhen during the nineteenth century and many of the works of these kilns were signed by the craftsmen. Amongst the best of these was Wang Bingrong. The similarity of this bottle to that illustrated by Kleiner and the sharpness and vigour of the design, convincingly suggest an attribution to the Wang Bingrong workshop

For a yellow-glazed example from the Collection of Arthur Gadsby see Sotheby's, New York, Fine Chinese Snuff Bottles, November 22, 1988, lot 1
