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:
wasn't in copyright in the United States due to being registered for copyright there (see Commons:Copyright tags#United States for most cases) and
was created prior to 1976 and published prior to 1978 — then it was out-of-copyright in Italy on the URAA date of restoration (January 1, 1996) (17 U.S.C.§ 104A) (in most cases; for all cases, see Template:PD-Italy/US). If so, please add {{PD-1996}} in addition to this copyright tag. If the image was created after 1975 or was published after 1977, please add {{Not-PD-US-URAA}}.
According to the Decree no. 321/1956 of June 18, 1956 Chapter 1 Article 7, non-artistic photographs were not expressly protected by copyright. Artistic photographs taken between 1956 and 1996 are protected by copyright for a limited term, as follows:
(b) 10 years since issuance for the author of an artistic photographic series
(c) 5 years since issuance for the author of an isolated artistic photograph
Of the aforementioned photographs, those whose term hadn't expired before 1996 received a considerable prolongation, according to the Romanian Law on Copyright and Neighboring Rights Law no. 8/1996 of March 14, 1996 Article 149, Paragraph 3, modified by Law no. 285/2004 of June 23, 2004, Article 128:
The length of copyright over works that have been created before the enforcement of this law and whose protection terms had not expired according to the previous legislation are prolonged to the protection term provided by this law.
Therefore, Romanian artistic photographs whose protection term expired before 1996 are now in the public domain. These include photographic series published before 1986 and isolated photographs published before 1991. As a courtesy, please credit the author whenever using the photograph.
