Where do I get/buy an image of the original EPCOT city plan?

[nocturnal9]

I'm decorating my home and I really want a poster of the original EPCOT city plan (e.g. not the theme park). I've had a difficult time finding either a place to buy it, or googling a high-quality image (high enough to print out at 3 feet wide). Anybody ever seen anything like this available/downloadable?
