on page 28 (also
here) of the June 1930 issue of Popular Science Monthly. That issue was both
published with notice and registered with the U.S. Copyright Office (
registration no. "B 76212"). However, a careful manual search of the renewal records for 1957, 1958, and 1959 found no renewal was recorded for registration "B 76212" or any other issue of Popular Science Monthly magazine in these years. This is consistent with UPenn's research which says that
no issues of Popular Science were ever renewed.
