Few things are ever cooler than a Michael Whelan cover, this time for Dragonflight.
This one just looks neat to me. By Hector. And I remember Garve as a good storyteller.
By Frank Frazetta.
Robert LoGrippo penned this one. Way creepier than the novel itself.
Powers of course.
By Robert Shulz. I like it because it’s from 1954, when even something as now unremarkable as Sputnik was pure SF, never mind an actual Mars colony.
