An ad for Detective Comics, November 1936

National Allied Publications started advertising their newest upcoming comic book title, “Detective Comics” in late 1936.  Above is a full-page ad inside New Comics #11, November 1936, though the magazine wouldn’t come out for three more months.  “Detective Comics” of course became the official name for the comic book company in the 1970s and years later featured the first appearance of Batman.
