Compare four similar iron wall hangings from the Shanghai Museum included in the exhibition, The Chinese Scholar's Studio, Artistic Life in the Late Ming Period, Asia Society, New York, 1987, Catalogue, no. 68, where tiehua, or iron pictures, are discussed. It is noted in the entry for no. 68 (p. 180) that they were made in imitation of paintings on silk and were meant to hang in a scholar's studio, the contrast of the dark metal design against the white-washed walls simulating monochrome ink paintings. Compare, also, other sets of iron 'pictures' from the collection of John Reilly, Jr. illustrated in The Romance of Chinese Art, New York, 1936 ed., pl. opp. p. 163
