Well Having seen a few of them most of the images 
of her aren't that great.  Only in a few places 
are there good shots of her(see yann's) other 
then that they are small very undefined images.   
The image does take up 50% or so of the cel and 
for not being a front on face shot I think its 
pretty good.  I wouldn't even be selling it if 
the economy didn't go put put flop.  But I have 
to agree with Yann, I don't think you are 
comparing apples to apples.  I also would love to 
see you post said information.  Heck I could say 
I've also saw a toto cel with matching background 
and signed by Miyazaki himself for $100.  But 
unless I produced something its just hersay.
