Nick Bantock, http://www.nickbantock.com,/ is one of the artists i really admire. I feel he is following his own road and doing his own, unique projects. One of his books, Urgent 2nd class, is just lovely.
He also has a rubberstamp-line, which used to be sold at Limited Edition Rubberstamps, but i do not know where they are sold now. The stamps are really unusual and gorgeous.
