This is a very very small double chop. The inscription which we haven't been able to decipher yet is very simple. We have more chops with such simple characters from the same source which makes us believe that they came from a dealer who had them inscribed to make them more commercial. The chop was acquired in 2013 and dates from the late Qing period (1644 - 1912) or early Republic (1912 - 1949). Length 1.45 cm. Width 0.9 cm. Height 0.9 cm. Weight 2.0 grams. The chop originally belonged to Rudolph Voll (1911-2009) who acquired it in the 1970’s in Hong Kong. For further information about Rudolph Voll see Quick Find 4167.
