When I saw the Pete Nebird byline on this Black Owl story from Prize Comics #6 (1940), I did a double-take. Not that comic book bylines of the thirties and forties can be trusted, since pseudonyms were more the norm than exception, but Nebird is Driben reversed.* Peter Driben, the world famous pin-up artist, that is. One look at the artwork of the Black Owl story disabused me of any notion that Driben had anything to do with it. Here is a Driben magazine cover from 1938:
Going to the Grand Comics Database, they give credit for the Black Owl artwork to Pete Riss and Jack Binder. Mystery solved. Besides Nebird being Driben backwards, it is also an anagram of Binder.
*It was the late Don Thompson who said (and I'm paraphrasing), comic book readers learn early on to read backwards.
