A WHITE JADE 'ZIZHENSHI YIN' SEAL QING DYNASTY, 18TH – 19TH CENTURY |

of square form, the upper section deftly carved as a mythical beast sitting on its haunches, an aperture pierced through its body below its horn, the seal face crisply carved with the four characters reading zizhenshi yin, the smoothly polished stone of even white colour

Collection of Edward T. Chow (1910-1980), and thence by descent in the family.
