This design appears to be inspired by the 'dragon' moonflasks produced at the Imperial kiln at Jingdezhen during the Qianlong period and is relatively rarely found on Imperial jade carvings. See a larger but closely related spinach-green jade vase and cover (41cm high), Qianlong period, with a very similar form and decoration in the Baur Collection, illustrated by P. Schneeberger, The Baur Collection, Geneva: Chinese Jades and Other Hardstones, Geneva, 1976, no.B91. Compare also a white jade vase with a similar form and a similar cover but carved with lotus flowers, Qianlong mark and period, in the Palace Museum, Beijing, illustrated by Yang Boda, zhongguo yuqi quanji: 2, Hebei, 2005, no.211. For other related jade vases of slightly different forms but also decorated with full-faced leaping dragons, see an example in the Metropolitan Museum of Art, illustrated in H. R. Bishop, The Heber R. Bishop Collection of Jade and other Hard Stones. Handbook no.10. New York, 1909, p.62; and another jade vase and cover with handles suspending loose rings in the Tianjin Museum, illustrated in Jade Wares Collected by Tianjin Museum, Beijing, 2012, no.186.
