Itty bitty flying saucers carrying giant human heads, why worry?
The cover of Night Of The Saucers by Eando Binder, author of Menace of the Saucers; published by Unibook, copyright 1971. Artists name is really difficult to make out… Perhaps John Cayon?
Text from the back cover:
It was Earth’s darkest hour. Weak, backward, prey to attack, it could only be saved by the Vigilantes. Sci-fi writer Thane Smith and his beautiful, adored wife Miribel, had the task of discrediting UFO stories. But how could they after they ran up against a playboy-monster who could only have been created by an alien race?
Yup, it’s just moved to the top of my reading pile.
