Term began: not parsed
Claimant: Popular science; J 3-1
Class: MP — published motion picture other than a photoplay (numbering series begun Sept. 1928)
Finding: no registration date parsed from the catalog entry

The catalog entry has a problem (missing date, or a number that does not fit its year), so the renewal check cannot be relied on.
