The design on the present bowl is based on a sketch sample issued by the Imperial Household Department and kept in the palace archives, as illustrated in Guanyang Yuci, Beijing, 2007, pp. 134-135, pl. 26. Bowls of such design were also made during the Jiaqing period. See for example a Jiaqing-marked bowl of almost identical size and pattern, ibid. Another closely comparable example was sold at Christie's Hong Kong, 28 November 2006, lot 1568.
