First off, let's start off with the entire scanned article from Comics Scene - I read it when I was 7. Still have it. All these scans are very big.

Then ...
I decided to scan everything from "The Animator's Survival Kit" that related to The Thief or anything that was on the additional discs we've been creating for this collection. (A Christmas Carol, the commercials ...)
All these scans are very big, and the goal is that if anyone wants to make custom covers for some of the extra discs, you'll find plenty of material here.

Some comments on some of this:
This donkey appears to be the Mullah Nasrudin's donkey, from the aborted Nasrudin film that eventually became The Thief and the Cobbler.

It matches the design seen on the cover of the Nasrudin book, perfectly. If so, this is the only real artwork I've ever seen from this project.
Here's an entire run sequence for the Old Witch. This animation appears in the finished Thief and the Cobbler film (the Princess version, anyway), but not in this form. The Old Witch's head has been redrawn - this would appear to be an early version of the animation, completed sometime before 1980, with a different design for the Old Witch. She has a longer nose, a little ponytail for hair instead of the bun, and more expressive eyebrows. Looking closely at the final version, it appears that the new design was traced over this animation ... sadly losing some of its quality because of that.

This changing of character designs when they'd already been animated happened a lot on this film. Phido in particular has had at least three designs that we can see in various documentaries and the workprint, and the final design is in some ways not as interesting, since it was simply traced over the old material. Early designs are evident all over the workprint for King Nod, Zigzag and The Thief.
(Incidentally, in many scenes in Who Framed Roger Rabbit, there's a newspaper prop "Toon Kills Man" showing an earlier design for Jessica Rabbit - she's blonde, has a much different face and a different dress which covers her breasts. It's even given closeups at times. Some scenes were reshot with a fixed version of the "pattycake photos," but the early jessica remains in many scenes. Suppose you could fix that digitally these days.)
