 Discovery site noted in Archaic Chinese Jades: Special Exhibition February 1940 (Philadelphia: The University Museum, 1940), cat. 28. Excavations at Anyang began in 1928. This discovery site is unlikely given the style of the object.
 Zhang Naiji (also known as N. C. Chang) was a businessman, born to a prestigious family in Zhejiang that made their wealth in the silk and salt industries. He collected ancient Chinese art objects and Chinese coins. Zhang amassed his collection whilst living in Shanghai, before leaving for America in 1938, and acquired his objects onsite of archaeological excavations (see Alfred Salmony, Chinese Jade through the Wei Dynasty [New York: The Ronald Press Company, 1963], p. 115).
Zhang lent his collection anonymously to Archaic Chinese Jades: Special Exhibition. We know his identity through letters housed in the Department of Archives, The University of Pennsylvania Museum of Archaeology and Anthropology, Philadelphia, Pennsylvania (see letter from C. T. Loo to Horace Jayne, October 25, 1939, and letter from C. T. Loo to Horace Jayne, December 16, 1939), copies in Freer and Sackler COM provenance files. The exhibition was entirely organized by C. T. Loo and Company, New York. Letters exchanged between C. T. Loo and the director of The University Museum, Mr. Horace H. F. Jayne, reveal that Zhang Naiji owned the objects and C. T. Loo and Company had the collection on consignment (see letter from C. T. Loo to Horace Jayne, May 28, 1939, and letter from C. T. Loo to Horace Jayne, October 23, 1940, copies on COM provenance files). C. T. Loo and Company kept the jade collection on consignment from 1940 through Zhang’s death in 1948, inventorying the pieces with a prefix “J” and labeling each item as “Chang [Zhang] Collection.”
 Zhang Mei Chien, Zhang Naiji’s wife, assumed ownership upon his death in 1948. She sold several pieces from her husband’s collection to J. T. Tai and Company in July 1954 (for example, see J. T. Tai and Company Stock
Record YT 886 and YT 895, copies in COM provenance files). It is unclear when Frank Caro, C. T. Loo’s associate and successor to C. T. Loo and Company, purchased items from Zhang Mei Chien.
 On September 1, 1952, C. T. Loo’s associate, Frank Caro (1904–1980) took over daily operations of the New York business, operating as C. T. Loo Chinese Art. Loo continued to play a large role in the business, as he and Caro struck a deal in which profits made on Loo’s stock would be evenly divided and Loo would maintain the lease and rental payments on the company’s gallery space.
 In 1961, Loo and Caro’s agreement ended. C. T. Loo and Cie., Paris, France, took control of C. T. Loo Chinese Art,
New York’s stock that C. T. Loo had added to the inventory before his death in 1957. Frank Caro then opened
Frank Caro Chinese Art. Caro acquired pieces from Loo’s original stock (the mode of acquisition is unknown). See Frank Caro Chinese Art invoice, August 27, 1964 (copy in object file) J 140: “Archaic jade miniature mask.
T’ao t’ieh [Taotie]. Eastern Chou [Zhou]. Height: 7 ins (Chang [Zhang] Collection).” This is the same stock number assigned to the object when C. T. Loo and Company had the object on consignment (see note 2).
 See invoice referenced in note 3.
 Pursuant to the agreement between Dr. Arthur M. Sackler and the Smithsonian Institution, dated July 28, 1982, legal title of the donated objects was transferred to the Arthur M. Sackler Gallery on September 11, 1987.
