I think I read on Studio Pierrot's homepage some time ago 
that there was going to be a special fair in Japan(of course
the fair's over now) where they would release the 
reproduction cels. You can try searching SP's webpage,
maybe they still have the news there. But what I'm 
wondering is, how much did those repros go for at the fair?
Surely not around 78,000 yen?
That, for _any_ reproduction cel, is way too steep.
