Hi ya'll - hope ya'll are having a wonderful day.

I recently acquired a 16x 20 foam board which has a sketch of the American Adventure Epcot Center World Showcase, in rough, then it has a completed drawing and then it has a completed pinback.

I bought this from a guy who was selling his parent's possessions. They were serious Disney collectors.

Anybody have a clue as to what this might be?

You may email me for a picture if you'd like.
