Colladay, Morrison M. WHEN THE MOON FELL
New York: Stellar Publishing Corporation, (1929). First edition, first printing: a chapbook original. Science Fiction Series No. 6. Chapbook. Penned checkmark and owner's name to front cover, covers show some age-darkening, thus a near fine example, in stiff, stapled wraps. Frontispiece illustration by the quintessential Gernsback artist, Frank R. Paul.
Entry in Hugo Gernsback's SF Series, not really a periodical, not quite a book. Colladay made a number of appearances in Gernsback publications (AMAZING STORIES, WONDER STORIES) during the early thirties.
