A similar you and cover with an inscription, Chen chen fu yi, dated to early Western Zhou, in the Harvard University Art Museums, Arthur M. Sackler Museum, is illustrated by J. Rawson, Western Zhou Ritual Bronzes from the Arthur M. Sackler Collections, vol. IIB, p. 491, fig. 67.3. Another similar you, in the Museum Rietberg, is illustrated by H. Brinker, Bronzen aus dem alten China, Museum Rietberg, Zurich, 1975-76, p. 68-9, no. 28. The strapwork cast in relief on these you is based on leather straps secured by diamond-shaped studs that would have been found on leather pouches or flasks of this period.
