NP [US?], Privately Printed [?], 1918. First edition, first impression. Paperback. A near fine copy. An uncommon publication, likely a vanity project. The author is not recorded, but the work is copyrighted to a Simon Wardwell. Only two copies located (in US universities, so likely a US publication). 105 pages. Subtitled From the Cave Man in One Thousand to the Cave Man in Ten Thousand. A little toning to the wraps, but otherwise in excellent shape. A future history yarn, from the perspective of a Martian visiting an over-populated future Earth. [9665, Hyraxia Books].
