Hi J-Decker,

I thought I'd speak up since I was the one who 
sold you the cel.  ^_^

Usually when matching cels to screenshots or 
artbook pics, a good way to see if they match up 
is to check places where the shading changes.  
However, on this cel, there's a little giveaway.

If you take a look at Tasuki's upper hand in the 
cel, you'll notice some correction lines painted 
onto the front of the cel, extending and 
connecting some of the lines in his palm.

Now, in the anime, when this cel appears, you 
can't even see his hand -- it's out of the shot.  
So, why would there be correction lines painted 
on a part of the cel that doesn't even appear?

If you look closely at the book, you'll see that 
the same lines (and their occasional mistakes) 
appear in the photograph of the cel.  They're 
quite distinctive, and they appeared to match 
exactly the last time I compared the two.  It's 
my assumption that the correction lines were 
added to the cel when  it was photographed for 
the book, to make the entire cel more 
aesthetically pleasing.

You may not be able to see the lines in the photo 
of the page that you have, and I regret to report 
that I no longer own my copy of the book either.  
But if you know someone who has it who can scan 
the page for you, or if you pick up a copy of the 
book somewhere, you'll see the same lines on the 
cel in the book.

Take care,

zenjirou
