I found these at a thrift shop. The chairs were stripped of finish and seat coverings were removed, but chairs are strong and in great condidition.
It appears that they are a hard wood; maybe elm, mahogany?
I inherited a tea set from my grandfather. I believe it was bought while oversea in the area of Japan during the 40's or 50's. The porcelain is almost see through. The painting on each piece seems to be mostly in gold. Nothing else known.
