Thank you for viewing. This is a commemorative necklace from the previous Osaka Expo, held in 1970 at the same location where the recent one just ended. I discovered it carefully stored in a safe. Others are exhibiting keychains, but I remember ordering a salesperson at the time and paying a high additional fee to have it changed from a keychain to a necklace. I would like to pass it on to someone who will cherish it. Thank you.
