Mikara99 sometimes exhibited Dojin cels of 
Princess Mononoke without any explanations. 
So i pointed you should explained the cel was 
not a production cel. Thereafter Mikara99 adds 
a sentense "This is a Dojin cel." 

By the way, Mikara99 has exhibited a beautiful 
San cel (600,000 yen) on Yahoo auction JPN. 
The scene is printed in many Mononoke 
magazine books. It is, therefore, one of the 
most famous scene in Princess Mononoke.

I am sure the cel is a production cel. The 
condition is not good, however. This is a 
misfortune for all Princess Mononoke cel 
collectors!!
