For those unfamiliar with Expo 86, the dome on the left was the theme structure Expo Centre. It's still in use today as a science museum. The monorail can be visited at the Alton Towers theme park in the United Kingdom. Sadly the rest of the colorful structures seen here have been lost to time.
My next book is on Expo 86 and I'm really enjoying going through my pictures for it. This was a great fair in a great city!
