Triplanetary

Quill & Brush warns explicitly that Fantasy Press "may have occasionally left 'First Edition' statement of original publisher on offset reprints with their imprint" — so the copyright-page statement alone is not sufficient. Always read the imprint on the spine, title page and jacket: a "First Edition" statement under any imprint other than Fantasy Press, Reading, PA is a carried-over statement on a reprint, not a first. The novel was later gathered into the Fantasy Press "History of Civilization" Lensman omnibus set (1955), which is a separate limited edition and not the 1948 first.
