These 2 guides are among my favorite collectibles.
This pamphlet from 1981 is all concept paintings and a description of the coming attractions for Future World and World Showcase. The artwork for Epcot is absolutely beautiful.
This Commemorative Pre-Opening Guide to Epcot Center, from 1982 has mostly construction photos with a few concept paintings from the pamphlet mixed in.
In a future post, I'll share the guide book.
