This is an antique Japanese military sake cup, decorated with a helmet with a pair of flags, one of which is the flag of Manchukuo. The words are "Victorious Return Manchuria Incident" and on the back "Showa 9th Year (1934) Yamagata Prefecture". I believe this cup was given to returning soldiers who participated in the war.

Condition: Excellent - light surface blemishes and small scratches of the gold paint

Size: 3.75" across
