Under a Glass Bell

No book-club issue. The tell that actually matters is the Gemor Press SECOND edition of the same year — 1944, limited to 800 copies, collating 86 pp against the first's 83 pp, also with the Hugo engravings. It carries the identical Gemor Press 1944 imprint and is routinely offered as simply "Gemor Press, 1944," so the limitation statement (300 vs 800) and the page count must be checked before a copy is called a first.
