Ralph Steadman is, well what is he? Cartoonist? Too small and trivial a word. Illustrator? Artist? Clear-eyed recorder of a fuzzy wonky world. Gonzo draftsman, collaborator of Hunter S. Thompson, author of piles of incredible uncategorisable books – including the whole history of the world and God, The Big I Am – surrealist, rationalist and friend of the New Humanist family.
