Public domain
This image (or other media file) is in the public domain because its copyright has expired and its author is anonymous.

Note: In Germany and possibly other countries, certain anonymous works published before July 1, 1995 are copyrighted until 70 years after the death of the author. See Übergangsrecht. Please use this template only if the author never claimed authorship or their authorship never became public in any other way. If the work is anonymous or pseudonymous (e.g., published only under a corporate or organization's name), use this template for images published more than 70 years ago. For a work made available to the public in the United Kingdom, please use Template:PD-UK-unknown instead.

The country of origin of this photograph is Italy. It is in the public domain there because its copyright term has expired. According to Law for the Protection of Copyright and Neighbouring Rights n.633, 22 April 1941 and later revisions, images of people or of aspects, elements and facts of natural or social life, obtained with photographic process or with an analogue one, including reproductions of figurative art and film frames of film stocks (Art. 87) are protected for a period of 20 years from creation (Art. 92). This provision shall not apply to photographs of writings, documents, business papers, material objects, technical drawings and similar products (Art. 87). Italian law makes an important distinction between "works of photographic art" and "simple photographs" (Art. 2, § 7). Photographs that are "intellectual work with creative characteristics" are protected for 70 years after the author's death (Art. 32 bis), whereas simple photographs are protected for a period of 20 years from creation.

This may not apply in countries that don't apply the rule of the shorter term to works from Italy. In particular, these are in the public domain in the United States only if:
