This is an antique Japanese military sake cup, decorated by some signal wire poles, a flag of the signal unit, a bird carrying the banner that says "Commemoration" and the insignia on the left with the words "Wireless" on it. The words on top are "Imperial Guards Signal 1st Regiment". It's interesting because the "wireless" designation is very unusual. Most of the time they just say signal units. The soldier's name Kawasaki is on the back.

Condition: Excellent - slight fading of the gold
