Black, Pansy E. THE VALLEY OF THE GREAT RAY
New York: Stellar Publishing Corporation, (1930). First edition, first printing: a chapbook original. Science Fiction Series No. 11. Chapbook. Penned checkmark and owner's name to front cover, otherwise virtually as-new, a near fine example, in stiff, stapled wraps. Frontispiece illustration by Ruger.
Entry in Hugo Gernsback's SF Series, not really a periodical, not quite a book, provides a tantalizing glimpse into early American SF. A Pansy Black tale also appears as SF Series No. 13, but no other titles have been unearthed by Bleiler or Reginald.
