Are these old sweets or perhaps bonus items? I couldn't find any information about them on Google, so their origin is unknown. They were stored with textbooks from around 1955, so I believe they are from that era. They are cards with illustrations of temples and tourist attractions on one side and explanatory text on the other. The case is tattered, and the cards themselves are yellowed and stained. Please purchase only if you understand that these are vintage items. Other...Showa Retro
