For a faceted, rectangular example see Robert W. L. Kleiner, Chinese Snuff Bottles, A Miniature Art from the Collection of Mary and George Bloch, p. 263, no. 205

It is interesting to note that an almost identically shaped bottle is illustrated by Hugh Moss, Snuff Bottles of China, pp. 140-141, no. 371, but is inside-painted by Gan Xuanmen, one of the early school of painters working between 1815 and 1823
