Takeshi Kitano's paintings in Hana-bi movie?

[Mario]

Hello ,

I am very much interested also in other works of Kitano
besides movies.

I am very much interested in buying books, postcards, posters or
anything related to Kitano's art work.

In the Hanabi movie they are seen in the beginning of the movie and
end of
movie as trailers if I am not wrong.

Do you know any web sites that show any of these paintings ?

Kitano's official web site is only in Japanese are there any non
official Kitano's web sites that show the paintings ?

Please let me know all you know about it and where can I buy them
from.

All your help regarding Kitano art work is greatly appreciated.

Thanks a lot,

Mario
