Question:

Were can I buy Hockimo Yoshura artwork?

Is there some place online, or is there an art dealer I can contact. I like his stuff, I just can't seem to find it anywhere.

I used to see his stuff in coffee shops in the northwest. If that helps at all. Its the pictures of cities that have been flooded (like if the ice caps melted).

I can't find it either.
Maybe it's something rare.

Why not try to seek help from any other dealer in Japan on other artwork.
