A clay inkstone and cover molded as a crouching tiger very similar to the present lot, of Qianlong date, are illustrated in Emperor Ch'ien-lung's Grand Cultural Enterprise, National Palace Museum, Taipei, 2003, p. 113, no. III-4. One can see in the illustration that the example in the Imperial collection also has mottled green patination in imitation of the green encrustation found on ancient bronzes.
Also illustrated, ibid., are several boxes that were specially made for valued objects in the Imperial collection. Some have finely carved decoration, as well as gilt-filled inscriptions: I-20, a box for two Imperial jade seals; I-41, a curio box; and II-19, a box for a jade cup.
