I love this cover. Note the white building to the left of Spaceship Earth - this was an early concept for the American pavilion which would have sat at the entrance to World Showcase in the 1978 design of Epcot!
You can see the placement of the American Adventure in the model here. Note the Land model is closer to the final version - whereas the painting is the earlier version as proposed by Tony Baxter.

Here is a closer look of Tony Baxter's original concept of The Land as portrayed in the cover art (which is a Herb Ryman painting, I believe)

This is a rarely seen view of the 1978 concept - as Epcot sits in reality with SSE at the North and WS to the South.

A look at the Future World pavilions - including the "Life and Health (later called Wonders of Life), Transportation (aka World of Motion -> Test Track) and the Space Pavilion (Shifted to Horizons -> Mission: Space)

The Space pavilion would have been AMAZING:
