Try checking with Lady Zatara. (a couple of 
threads down). Not only has she sold me a number 
of beautiful cels of the unicorn but she also has 
some amazing sketches as well. I don't know if 
she has anything she wants to sell right now but 
it might be worth checking.

I guess I can also use this opportunity to 
publically thank her for this lovely cel of Mommy 
Fortuna. She so wonderful I still can't get over 
it. ^_^
