Someone posted a related topic on beta awhile 
back.  There's some seller who's been posting 
auctions with other people's DBZ cels on them.  
We saw a couple auctions with cels from the Last 
Saiyan's Cel Gallery.  EXACT!  When questioned 
about it on auction the seller claimed they were 
two different cels, but couldn't explain away 
the sequence match.  Total scam.
