Space Adventures #4

Steve and another prospector are confronted by the landowner when they discover a meteorite filled with diamonds. All three are killed when they shoot it out. Two men arrive at the scene and conclude nobody will bother with the meteor as they walk away. The meteor opens and the real owner of the meteorite peeks his head out. It is a space traveler with wings and a mechanical box on his chest. He says the meteor was his and he had brought it all the way from Jupiter.
