A very similar pendant but with four entwined snakes is in the Seattle Art Museum, illustrated by J. Watt, Chinese Jades from the Collection of the Seattle Art Museum, Washington, 1989, p. 69, no. 45, where the author describes the motif as an anchaistic revival from the Warring States period. Compare also another similar slight variation on the form on an example exhibited by Bluett & Sons, Chinese Jades from the Mu-Fei Collection London, 1990, Catalogue no. 59.
Two similar pendants from the A.S Reynolds Collection, one ivory, the other jade were included in the Oriental Ceramics Society and Bristish Museum exhibition, Chinese Jades from the Shang to the Qing, London, 1984, nos. 237 and 238.
