We got confused trying to figure out what really happened to Future World but the lead entry in Google told us:  “Future World is (was) one of two “lands” at Epcot at Walt Disney World Resort, divided into two sections, Future World East and Future World West… A unique feature of Future World was its inclusion of a monorail track in the park.  Replaced by: World Celebration; World Nature.   Opening date: October 1, 1982;  Closing date: September 30, 2021.  The unused postcard’s still here, and Grade: 1
