Harvey Films, who acquired the post-October 1950–March 1962 Paramount's Famous Studios animated short films library, did not file a copyright renewal for registration within the required 28-year period between 1980 and 1981.
No results, excluding irrelevant works in different classes and owner transferrals, are found online.
It entered the public domain on the first day of January 1982 after the failure of copyright renewal.
It is freed from restrictions and is permitted for anyone to redistribute, sell, modify, and remix it in both formats legally.
