Mark's "little books" are lovely snapshots of his various obsessions. I picked these up a very long time ago (hence the slightly battered quality) and I'm really happy to see he's still going strong. His mix of ephemera, collected/found items, printing/production techniques and disposable culture makes the books and prints wonderful tactile objects.
For more wonderful craziness, check out his brilliantly retro website (even has a .demon domain!): http://www.mpawson.demon.co.uk/
