Compare to an identical vase of almost the same size in the Baur Collection, illustrated by John Ayers, Chinese Ceramics in the Baur Collection, vol. 2, Geneva, 1999, no. 302. An identical pair of vases from the Millicent Rogers Collection was sold at Christie's Hong Kong, 28 November 2012, lot 2128. Another very similar pair, conceivably the present pair, was illustrated in The J. Insley Blair Collection of Chinese Porcelain, New York, 1925, pl. 1.
