I recently asked paper artist Linda Toigo to tunnel through a copy of Secret Tunnels of England: Folklore and Fact and this is the result. You can see more of her work here. Down to under 100 copies left, so get yours soon. Available through Amazon, and Watkins, Treadwells and Atlantis, LRB Bookshop in London, Five Leaves in Nottingham, Albion Books in Hastings and the Bookkeeper in St Leonards.
