London: Haycock Press, No date. [1941.]. First edition. Spine a little worn; ownership inscription, dated 1941, on endpaper; else a very good copy of this scarce first edition. In 1943, having been gifted to The Daily Sketch War Fund by the authors, the book was reprinted on thinner paper. The figure of Hitler on the front cover was altered to show Hitler wearing only one armband. The second edition is considerably more common, having been printed in far greater numbers than the first.
