It was previously considered to be in the public ___domain because it is a scan (or similar) by the Bibliotheque Nationale de France, but not everything scanned by the BNF is automatically in the public ___domain.

It is possible that this file is in the public ___domain for other reasons, for example because it was published a long time ago (anything before ca. 1900 is most likely ok) or because its author / artist / photographer died over 70 years ago and it was published over 95 years ago. In such cases, a new rationale should be applied, and a different license tag (see Commons:Licensing and valid license tags at Commons:Copyright tags) should be used.

If the file is not found to be in the public ___domain, it might be nominated for deletion (NOT by any automatic process, but manually).
