A white porcelain yunomi (teacup) by Han Ikhwan, a Korean Living National Treasure (Human Cultural Asset). This is a set of four. Han Ikhwan was a popular ceramic artist in Korea, and his works have become difficult to obtain since his passing. This is a valuable item. Three of the cups have not been used, but one has some age-related staining on the underside. There appear to be some cracks (known as "nyu" or "crazing") in the ceramic. Overall, the condition is very good. Please check the photos. Size: Height approximately 6cm, Diameter approximately 9cm
