I asked him this...

Hi,
    Just wondering if you actually own this cel? 
I ask this because It is at another cel gallery 
for sale for $430. It is the same exact cel but 
it looks like your picture has been dulled once 
in a image editor.

Here is his response...

Yes, I actually have it. It's really cool but I'd 
like to sell it now so I put it on ebay.


The images are EXACTLY the same except he went 
into something light photoshop and dulled it one 
time.

Notify ebay about this, its all that can be done.
