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).
See below for the previous rationale (not applicable anymore).

This is an image of a page or pages from a collective work such as a newspaper, magazine or encyclopedia that is in the public domain in its country of origin (France) and in the United States. It is not known to contain any legible non-free content. However, the date of death of some of the individual authors is unknown, so some of the text or pictures may be non-free. Do not crop this image to extract selected content without first confirming that this content is in the public domain.
