Purchased from an antique shop. It's from around the Showa 30s (early post-war period), and it's said to be a bag children used when playing "train." Size: Width: Approximately 20 cm Height: Approximately 14 cm Made of paper. There are gaps in the box. (Please check the images) I thought that repairing it would decrease its value as a historical artifact, so I left it as is and displayed it in a clear plastic pack. I believe it's quite a valuable item. How about it for those who are looking for one?
