I'm glad you like shin-chan. I am a fan of anime 
series like crayon shin-chan, Bono-bono, Chibi 
maruko-chan, arare-chan which are thought 
childish (no offense, but I was told how a grown 
up like me can like those anime ). I have seen 
somecels ( even with matching BG ) in YJ. I 
remembered they usually went around Y 3,000. But 
I never seen any in cel dealer's sites. I hope it 
will help you.
