A follow-up! I found a reference online that suggested Popular Science had failed to file the then-required copyright renewal for its magazines. The U of Penn has digitized all the renewal books, the official source. For 1940, there would need to be a +28 renewal (could be 67, 68, or 69). No renewals for any issues any year. Suck up, PopSci, those are in the public domain.
