IOPS has talk to do more books.
There was some discussion with one swedish artist, possibly book of my own sometime when I feel like it, who knows in BU returns with new never-before-seen material, next book in color.
Due personal interest and possibilities, I may start putting out more books in future.
Not to hijack the topic for non-BU related, but I did also 3 books of cult artists Nalle Virolainen back in 2007
+ two postcard books (full color postcards binded together)
Books are 70 pages of images, 30 pages of text in Finnish. They are b/w drawings, totally amazing, totally original. If this guy was international artists, he would be probably hailed together with Mike Diana and many of other naive, but perverse graphic artists. His paintings are even better. All books still available, 10 euro each. Not bad for 100 pages release.
I did also some other stuff, but those only interests of Finns, due language.
