Clips are not offered for this film: a public-domain mark that nothing bears out (no year, or a year no US term has left).

Not offered: its uploader or archive marks it public domain, and nothing the site holds bears that out (its record gives no year, or a year from 1978 on, which no US term has left), so where it is free is not known. Unclear is not offered. Open it at the Europeana.
