That it is up to the buyer to be aware of what is 
on the market.  Many times I have seen faked 
mononoke cels on YJ go for quite huge sums.  Even 
with faked sequence numbers, its easy to tell the 
difference when you see a scan close up.

In my dealings with Mandrake they always been 
curteous, helpful, and kind.  A few of my friends 
have purchased mononoke cels from them and they 
are *beautiful* and quite legit.  Like others 
stated here, from my experience with these 
people, I would raise serious doubts that they 
have done this intentionally.
