See a celadon-glazed bowl of comparable shape and mark, together with a matching cover, from the collection of E.T. Hall, sold at Christie's London, 7th June 2004, lot 33 (part lot). Vessels with the same mark, celadon glaze and brown rim also include a bowl and a dish in the Sir Percival David collection, now in the British Museum, London, the bowl included in the Victoria and Albert Museum exhibition, op.cit., cat. no. 47, and the dish published in Margaret Medley, Illustrated Catalogue of Ming and Qing Monochrome Wares, London, 1989, coll. no. A568; and a covered bowl sold at Christie's Hong Kong, 29th May 2007, lot 1545.
However, not all vessels with this mark are celadon-glazed which may be due to the continued use of the hall for several generations and the subsequent later production of porcelains; see a vase covered with a brown glaze in imitation of a bronze vessel, illustrated in Qingdai ciqi shangjian [Appreciation of Qing Dynasty Porcelain], Shanghai, 1994, pl. 151; and a pair of blue-glazed cups and saucers sold at Christie's New York, 18th September 2003, lot 355.
