Cels Forum

I have a bit of a problem regarding a cel I recently 
received, and searching through the archives of this forum
didn't really turn up anything, so I'm turning to the 
collective wisdom here :-).

This cel is two layers. It has very obviously been stuck 
together in the past and separated, as there is a good bit
of paint from the top layer all over the front of the bottom
cel. Surprisingly, this really hasn't damaged the top layer
that I can see.

After separation, a layer of rice paper was put in between
the cels, and as expected, it's adhered to the top layer
quite well. Unfortunately, this rice paper really obscures
the bottom layer, to the point where it's very hard to see.
It's also starting to stick to the adhered paint of the 
bottom layer.

I've been trying to determine what to do about this. I don't
care if multilayer cels stick together - they're all one 
picture to me :-). If I tried to tear away the rice paper
from the areas where it's not stuck, how would I go about 
doing this so as not to damage the cel it's stuck to? Any 
other thoughts or opinions? I haven't done anything with this
cel yet, other than think about what can be done :-). Thanks.
