Man O' Mars #1

An anthology featuring two science fiction adventure stories: "Man O' Mars," in which a space explorer in a red suit and helmet battles green Martian aliens aboard a spacecraft over Mars; and "Star Pirate," following a space-rover pilot named Star who infiltrates the office of a wealthy Martian named Manvid Brakon to gather intelligence on a kidnapping plot and mining industry scheme, encountering guards and traps while navigating an underground facility. The second story involves a "Space Ranger" character operating detector equipment and dyno-tubes to combat small green alien invaders.
