Term began
1946-02-01
Claimant
2c 4-19-46, synopsis
Class
MP — published motion picture other than a photoplay (numbering series begun 1946)
Finding
no renewal entry found for 1973-1975 in the CCE motion-picture renewal sections
In the public domain since
1 January 1975 (end of the 28th year, no renewal)

A renewal would have appeared in the Copyright Office's renewal registrations 27 to 29 years after the term began. Those volumes are loaded and no matching renewal was found. A work published 1931–1963 that was not renewed entered the public domain at the end of its 28th year.

A renewal had to be filed in the 28th year and would be listed in the 1973 or 1974 volume; volumes searched: 1973, 1974, 1975.

The renewal sections are OCR text of printed volumes; a damaged record can hide a renewal. Before relying on this, search the linked volumes yourself for the title and for number MP437.
