One of my absolute-favorite movies in college, and
one of the first things on my list when I found
out about the commercial availability of animation
art.  Unfortunately, none of the US dealers I've
purchased from over the years have ever been able
to lay their hands on any.  You would think
there'd be storyboards and layout sketches, if
nothing else.

Ah, well, the search continues.  Maybe I'll find a
Ralph The All Purpose Animal sketch in another 15
years... :)
