Hull describes his (self-published?) book as a "supplement" and "errata" to Jytte Klausen's book The Cartoons That Shook The World, as Hull includes Mohammed caricatures which were removed by Klausen's publisher. However, Klausen has not endorsed Hull's publication, and the two books have no official connection. The books Blasphemy and L'Affaire Des Caricatures provide more insightful coverage of the debate surrounding images of Mohammed.
