What's really going on in this cover --
Imagine life ten years from now. A man and wife take a vacation to Venus. The husband thinks that it would be the perfect time to finally get rid of his 'pain in the neck'. With one quick, clean shot. He climbs out of the spaceship and, as his wife is admiring the flora, he lifts his rifle and takes aim.
Suddenly, out of the brush comes an enraged Venusian bull space-elephant ! Just in the nick of time, the wife leaps out of the way of the Venusian bull space-elephant, and the crosshairs of hubby's hunting rifle.
