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.
In order to be hosted on Commons, all works must be in the public domain in the United States as well as in their source country. The copyright of all Algerian photographs and works of applied art published prior to 1948 had expired in Algeria on the date of restoration (April 19, 1998)pursuant to the provisions of Article 60 of the defunct Ordinance No. 97-10 of 6 March 1997 which was in effect at the time. Such works are thus currently in the public domain in the United States.
