Vases of this shape and decoration are extremely rare and no other example from public or private collections appears to have been published. The fine definition and details of the cloud design can be compared to several larger doucai enamelled moonflasks decorated with clouds and dragons, such as the example sold in these Rooms, 1 May 1995, lot 699; one from the Victoria Dreyfus Collection sold in New York, 23 October 1976, lot 316; and another sold in London, 20 June 1986, lot 278.
