Hello all!

   I have a cel that I'm thinking about 
selling/auctioning--my dilemma is that I really 
like the sketch.  Is it a generally frowned upon 
practice to sell the cel and keep the sketch?  I 
would obviously sell the cel for less without it, 
but it's been a number of years since I've been 
an active buyer/seller so I wanted to double 
check the ethics. ^_^  Thanks much!
