This media file is in the public domain in the United States. This applies to U.S. works where the copyright has expired, often because its first publication occurred prior to January 1, 1930, and if not then due to lack of notice or renewal. See this page for further explanation.

This work is in the public domain in France for one of the following reasons:
Its author (or the last of its authors in the case of a collaboration work) died more than 70 years ago (CPI art. L123-1) and did not benefit from any copyright extension (CPI art. L123-8, L123-9 and L123-10)[1];
It is an anonymous or pseudonymous work (the identity of the author has never been disclosed) or a collective work[2] and more than 70 years have passed since its publication (CPI art. L123-3);
It is the recording of an audiovisual or musical work already in the public domain, and more than 50 years have passed since the performance or the recording (CPI art. L211-4).
Please note that moral rights still apply when the work is in the public domain. They encompass, among others, the right to the respect of the author's name, quality and work (CPI art. L121-1). Attribution therefore remains mandatory.
↑Copyright extensions must be considered only in the case of musical works and of authors Mort pour la France (died during conflict, in the service of France). In other cases, they are included in the 70 years post mortem auctoris length (see this statement of the Cour de Cassation).
↑The collective work status is quite restrictive, please make sure that it is actually established.
The copyright of this image has expired in the European Union because it was published more than 70 years ago without a public claim of authorship (anonymous or pseudonymous), and no subsequent claim of authorship was made in the 70 years following its first publication.
EU
To use this template, the image must meet both of the following two conditions:
published over 70 years ago, and
the original author's actual identity was not publicly disclosed in connection with this image within 70 years following its publication.
Images that lack either of these two conditions should not use this template.
Reasonable evidence must be presented that the author's name (e.g., the original photographer, portrait painter) was not published with a claim of copyright in conjunction with the image within 70 years of its original publication. Works which had not entered Public Domain in their country in 1996 that were uploaded before 1 March 2012 should be marked additionally with {{Not-PD-US-URAA}}.
Note: In some countries anonymous works are copyrighted until 70 years after the death of the author if the author's identity became public in any way during the original term. In Germany this applies to certain works published before July 1, 1995; see Übergangsrecht.
