Detective Comics
Detective Comics is an American comic book series published by DC Comics. The first volume, published from 1937 to 2011 (and later continued in 2016), is best known for introducing the superhero Batman in "Detective Comics" #27 (cover dated May 1939).
The Shadow
During the mid-1970s, DC Comics published an "atmospheric interpretation" of the character by writer Dennis O'Neil and artist Michael Kaluta in a 12-issue series (Nov. 1973 – Sept. 1975). Kaluta drew issues 1–4 and 6 and was followed by Frank Robbins and then E. R. Cruz. Attempting to be faithful to both the pulp-magazine and radio-drama character, the series guest-starred fellow pulp fiction hero the Avenger in issue #11. The Shadow also appeared in DC's "Batman" #253 (Nov. 1973), in which Batman teams with an aging Shadow and calls the famous crime fighter his "biggest inspiration". In "Batman" #259 (Dec. 1974), Batman again meets The Shadow, and we learn The Shadow saved Bruce Wayne's life when the future Batman was a boy and that The Shadow knows Batman's secret identity (he assures Batman, however, that his secret is safe with him).
