File X (1)
July 19, 2010
Originally published in 1974 as The Secret Galactics. In my eccentric periodization scheme, “midcentury” lasts through the end of the Sixties (1964-73), so I’m cheating a little by including this title. But I love the cover illustration.
Bonus: More editions, below.
First in a series of ten posts showcasing my collection of midcentury paperback books the titles of which include a free-standing letter “X.”
