Hi!
Unfortunatly none of the artwork was released
infact I think it was destroyed ;_;

I was able to find a lot on YHJ a while ago but
thats the only place I've ever seen them.  Best
advice is just keep your eyes open on YHJ and
Mandarake and maybe some will popup again.  Just
be prepared for a bidding war!  ^_^
Good luck!
