This just in from Jim Korkis:
[Shortly before her death, Betty Kimball got rid of a lot of Ward's stuff. Often she would just box up everything related to a particular project in a single box and sell that off. One friend of mine purchased the box with all the information and artwork on Epcot's WORLD OF MOTION and there is so much of it that he is considering creating a website to showcase it all.
On eBay this week, it looks like some other fellow got a box filled with Ward's work on "Mickey's Madhouse/Mickey's Movieland" that was going to be an element of a movie pavilion at Epcot to be located between The Land and The Imagination pavilion. That project later expanded into the Disney MGM Studios theme park but unfortunately without Ward's attraction. Here is the link to some of that paperwork. I hope whoever buys it shares some of it with the rest of us.]
