Thomas Schostok....a few years ago we featured him in our little zine Art Erratica. He was generous enough to share hi-res scans of his work across the seas from German to our little production. He does really loose collage and gluebooks. Gluebooks. We don't generally call our books gluebooks over here in the states...at least I don't. It is an interesting and descriptive term tho.
He did these books a few years ago. I am not certain what he is up to at this point, altho from the looks of his site, he has a bit in print these days. His site is definitely worth a look. And follow the links to his Gluebooks for a really radical viewpoint.
