This crest was also said to be a Korean
Royal family crest. Note that it has the
16-petal Chrysanthemum of the Japanese
Royal family. This set also sold for a
princely sum.
I must put this cup first, as it might be the
most expensive cup I have witnessed being
sold. It sold for around $700 here in Japan.
The crest matches the one on the wood
box. Said to be the Korean Royal family
crest during the Japanese Occupation
(1910-1945).
