Ancient Astronauts (periodical)

Ancient Astronauts (a.k.a. Official UFO Special: Ancient Astronauts) is a twenty-five issue English-language magazine that was published from 1975 through 1980 by Myron Fass's New York-based Countrywide Publications. It was devoted to, as you might suspect from the title, the ancient astronaut hypothesis, inclusive of any number of speculative claims or "received wisdom" regarding visitations by advanced spacecraft in bygone days and their influence on ancient human civilisations.
