The picture below shows a larger view of all (3) Old Matching Occupied Japan Miniature Metal Bowls With Flowers in this lot. These bowls are not dated but they would have been made in the late 1940s, just after World War II. The maker is unknown. These are identical and one was flipped over to show the bottom. There is a design inside and they look like they are made of pewter or lead. They are marked on the bottoms as follows:
MADE IN OCCUPIED JAPAN
The bowls each measure about 2-11/16'' wide. They appear to be in near mint to mint condition as pictured.
