I dunno, but lots of illegal things get sold on 
Ebay everyday, like some of those...gah, can't 
spell it, those comics done by fans and people 
love to buy. It sounds like Doushi-something. 
Those are illegal to sell, but it is done 
anyway...guess like if you make anything fan-
based, you can't sell it-I think...dunno how much 
I'm right or wrong, because the cold took my 
brain away-but read it once on a fan site a while 
back... Dunno if fan cels are legal to sell, but 
people draw things and sell their drawings. I 
don't think that can be done either. Like taking 
something of another character and painting it 
and then selling it. I've heard of cases like 
involving Disney of people doing that and Disney 
sueing. I dunno. I've seen fan cels on Ebay, but 
then again, it seems a lot of things get sold on 
Ebay that might not be legal, but it's tolerated 
and allowed. *shrugs* Maybe a lawyer or someone 
knowing this could answer that, but that's my 
take or thoughts on it. ^_^
