The Rigid Tools poster wouldn't be too hard to reinsert into the original since it's only a few frames in the animation and it's part of the background painting rather than some sort of cell or animation element. Is the image above the best that's out there, or are there any higher resolution frame captures?

I'm about halfway done restoring the altered frames from the Jessica Rabbit panty shot scene. The latest edit to the scene actually removes the panties from her butt and makes it look even more like she's not wearing panties than the original did. Seriously, Disney?
