I have three auctions of production sketches on 
eBay.  The first is a genga set of Kuririn and 
chibi Gohan from DBZ, the second is a douga of 
the main trio from a cut scene in Outlaw Star, 
and third is a douga of Tamahome from episode 51 
of Fushigi Yuugi.  Please visit link above for 
these and other auctions.
