A special stamp book for collecting commemorative stamps from EXPO '70, containing stamps from various countries. - Title: Commemorative Stamp Book - Event Name: EXPO '70 - Countries: France, Australia, Germany, United States - Countries: Saudi Arabia, Canada, South Korea, Quebec - Total Pages: 75 pages I found this while organizing things at home. Based on a visual check, stamps appear to be present on over 80% of the pages (though please note that I haven't counted them precisely). As a souvenir from the Osaka Expo over 50 years ago, this should be a rare item for those who collect such things. Thank you for looking.
