More subtley streaked vases of this type, shape and with a Qianlong mark have been published: one from the collection of Sir Alan and Lady Barlow was included in the O.C.S. exhibition, Monochrome Porcelain, London, 1948, no. 94; another was included in the exhibition, Qing Imperial Porcelain, Art Gallery, The Chinese University of Hong Kong, 1995, no. 64; and one is illustrated by M. Beurdeley and G. Raindre, Qing Porcelain, London, 1986, col. pl. 210.
The shape and decoration of these vases is most likely based on Song dynasty junyao prototypes such as the boldly splashed bottle vase in the Freer Gallery of Art illustrated in Oriental Ceramics, The World's Great Collections, Tokyo, 1981, vol. 9, col. pl. 12.
