Bowman produced these beautifully painted trading cards beginning in 1951: Jets, Rockets, and Spacemen! The “jets” cards merely showed normal airplanes with informative text on the back, but the rest of the series told a story about a fantastic space adventure, with each card as a chapter.
The slideshow below features some of my favorites. You can find a complete collection of both the fronts and backs of these cards, so you can take the entire journey, at http://www.lowellsplace.com/jrs/jrs_main_page.html
Though I only heard about these cards this year, the series is clearly a direct ancestor of the Meteor Mags stories. Its conception of space involves pirates, cats, octopuses, and dinosaurs (flying reptiles, actually: pteranodons). That’s my kind of space adventure!
Octopuses in space!
Vicious cats on other planets!
I love keeping up with current developments in space exploration, but I guarantee you that interplanetary travel will never kick as much ass as it did in 1951! Tragically, this series stopped before the complete story was told.
