Actually I do sign my fan cels in permanent pen, 
they do not have any production holes, & they 
aren't even standard cel size. Not to mention the 
plastic sheeting I use if slightly thicker. I'm 
even working on my own stamp with a company logo. 
I do everything I can to avoid confusion about 
whether or not my cels are real. I want people to 
know their repros. That's the whole point. I am 
trying very hard to keep situations like this 
from happening. One customer violated my terms of 
service & I will no longer create cels for him.

  Thanks! ^_^
