Ok, I thought this would never happen, but eh-heh 
apparently I was mistaken.  

I've had some cels I've done on commission be 
resold before, but hey, they were marked several 
times as a repro, so it was alright with me.  

But let's say a repro I've done is being resold 
with a mention that it's a repro cel (once) 
otherwise descibed pretty much like its a real 
cel (like no 'repro' or 'fancel' mention in the 
title) and um... the size of the cel being sold 
is different than the size it was originally, 
which leads me to believe the signature has 
been removed by cropping the cel an inch on each 
side...

I'm not using names 'cuz I haven't recieved a 
reply from this individual yet.  HOWEVER, what 
should I do if they don't reply?  Email the 
bidders?  I don't want anyone to get screwed over 
by one of my pieces, and it's already selling for 
quite a bit for a simple fancel, which I really 
don't think it would if the signature was still 
there, or if it were more clearly marked.
