Hello,
I don't think that everybody use the term
"hanken mono". Usualy we just say "hanken cel"...

I have two from Project A-Ko that I may sell
if you are interested. They are already framed.
As I am leaving for Japan in a few hours, I
can't scan them right now but I will do it
when I am back.

Cheers,
Yann Stettler
