mmm, alot of my friends are saying that's a too high price for the framing. So I think I'll shop around a little.  As to what character it is, I got it from Van Eaton galleries. It wasnt cheap, but its a cel I've been looking for for a while (you can find their site online).  It's Mrs. Brisby reading the inscription on the back of the amulet, with nicodemus' hand also inframe. :) 
that's a small scan of it.
