The Shadow 1941: Hitler’s Astrologer (1988) was one-shot graphic novel published by Marvel Comics. It featured the art of one of my all-time favorite artists: Mike Kaluta (aka Michael Wm. Kaluta). The Shadow started out in pulp magazines and was a radio serial favorite with the tag line The Shadow knows… Its copyright must have either fallen into public domain or is easy to negotiate because Kaluta drew (and wrote) this character for DC Comics, Dark Horse Comics and Marvel Comics.
Writers: Denny O’Neil and Michael Kaluta. Inker: Russ Heath (a legend as a pencil artist too). Lettering: Phil Felix.
