This fab link from the Cartoonist regarding Russian pavilion designs got me thinking about my trip to the Expo' 70 Word's Fair in Osaka, Japan. It was an incredible experience for a 10-year old boy. The architecture at the fair was like something out of the City of Domes from Logan's Run (unfortunately, I was there with my mom, not Jenny Agutter).

Even though I never managed to attend any subsequent World's Fairs, I can still see what I missed with this convenient World's Fair and Exposition Information and Reference Guide.
