I wish I had the cel's now that I had back when 
I went to an anime convention eairlier this 
year. I would of definatally got a couple 
signed. When I was there the voice actor of Teen 
Gohan (Kyle Herbert) from DBZ, was asked to sign 
a cel and he was very careful not to mess up the 
image and signed in the blank space around the 
cel. I think signatures would make the price go 
up ,if its not all on the cel image.
