I have had a few of this type over my 50+ years selling and have always found them INTERESTING, UNIQUE and CLASSIC being made in the JIANGSU PROVINCE (100 miles west of Shanghai). Formed with fine ZISHA CLAY as a XIXING TERRACOTTA QUAD HANDLED VASE with FINELY INCISED CHINESE DRAGON SURROUNDING THE 6" VASE --- Unmarked, so probably not made for export at the time. Their main industry were the TEAPOTS that are now highly sought.
NICE FIND and I will have a VERY FAIR ASKING PRICE for an example NOT EASY TO FIND!
