Well, because I'm a freak and I hate stuff like 
this I e-mailed the seller for a better scan.

It definitely looks like a copied transparency 
from here (in my humble opinion).

If that's your same cel number drawn on it, I'm 
going to die laughing! (though I haven't seen 
many main cel images labeled 'B' either...)

Maybe asking the seller to stop the auction is a 
little ambitious.  Why don't you just ask her to 
put the truth in her auction-an office 
transparency rip-off is NOT a cel.
