I've come across a lot of truly bizarre stuff on ComicBookPlus, but this one takes the cake. It's Rudy Palais again (we saw him last week with Devildogs Three) and this one is even better! The cover and ad way down below are believed to be by Reed Crandall. At the end of the story we're promised another adventures of Futuro in the next issue, but there was no next issues, robbing poor Futuro of his promising future. It's from Great Comics #3, Jan. 1942, and it's a rangerhouse scan.
