I was looking around for DBZ cels on ebay, and on 
yahoo japan, and I came across the same cel on 
both.  I have dealt with the seller on ebay, and 
find him a good seller, and the YJ seller has a 
rating of 584, could they be the same person, I 
do not know.  Here are the links for the two 
auctions:
