Square cloisonné vase with taotie decoration, China, 18th century, polychrome cellular enamel on copper core, fire-gilded. Openwork figural handles. Under the base an engraved 4-character Qianlong mark plus an additional character in the line below (probably a numbering identifying this vase as part of a set).
