This superhero yarn from Four Favorites #8 (May; 1945) was published by Ace Periodicals. I've previously posted two other stories from this issue featuring Lash Lightning & Capt. Gallant, but it has been awhile since they appeared here in the Catacombs.
Magno and Davey were created by golden age writer Paul Chadwick, who shares a name with a contemporary comic book guy (the creator of Concrete; published by Dark Horse), but there is no apparent connection between the two Chadwick's. Trivia is fun stuff isn't it? Maybe this is just an example of Earth 1/Earth 2. Ya' never know!
Upcoming on the blog will be more adventures of Rulah Jungle Goddess, the return of my "Gal" Friday feature and a few reviews of upcoming comics & films. Oh, and more "1970's Flashback" stuff. Joy!
