Skot, have you checked out Ralph McQuarrie's web page:

http://www.ralphmcquarrie.com/gallery_1/star_wars/tv_special/

I can't figure out how to get a closer look at the gallery images, but a few I don't think I recognize. (It's hard when I'm squinting at something the size of a small postage stamp.)

The paragraph to the left is a short summary of production and why it turned out a ghastly mess.

(Ah, never mind, just went back to the main page: "PLEASE NOTE: All thumbnails will eventually become clickable pop-ups.")
