I saved these when a family member passed away several decades ago - they were wrapped in tissue and stored in a small box for decades.  They were brought back from her spouse who was stationed there in the service.  

As you can see in the second photo, both of them still have the Japanese sticker still on them.  The one on the left is approximately 17" square and the one on the right approximately 15" square.

They have always been stored in homes that are smoke free and pet free.   All sales are final - please message me with any questions before purchasing.  Thank you.
