【EXPO '70 Japan World Exposition Site Map】 This is a handkerchief featuring the site map of the 1970 Expo. It's made of smooth polyester, so it likely won't absorb much moisture, but I'm listing it as a handkerchief. It's a square, approximately 38cm on each side. Please check the photos: the 6th photo shows slight yellowing, and the 7th photo shows black and blue stains. The colors have faded overall, but as you can see in the last photo, the text is still readable. #1970Expo
