The “Good Books Worth Reading” was a regular feature across the DC books in the early 1940s, part of an initiative to make sure them funny books weren’t corruptin’ kids’ minds! This one, from COMIC CAVALCADE (1942) #2 shined the spotlight on George Lowther’s “Adventures of Superman.”
Historical notes: Just nine days after the release of this issue, the sixth Superman cartoon produced by Famous Studios was released, having taken over production from Fleischer Studios. It was the 15th short overall in the series. The short, titled “Jungle Drums,” is now in the public domain and can be downloaded at the Internet Archive.
About a week later, the Man of Steel got another animated nod in the Warner Bros. Merrie Melodies short, “Super-Rabbit.”
The approximately 8-minute-long cartoon was written by Tedd Pierce and features “rabbitus idioticus americanus” Bugs Bunny eating a scientifically engineered “super-carrot” and gaining powers and abilities far beyond those of mortal wabbits, — er, rabbits.
