이 작품은 미국, 그리고 저작권 보호 기간이 저작자 사후 70년, 또는 그 이하인 모든 국가에서 퍼블릭 도메인입니다.
You must also include a United States public domain tag to indicate why this work is in the public domain in the United States. 일부 국가는 저작권을 사후 70년보다 더 길게 적용하고 있으므로 주의가 필요합니다. 멕시코는 100년, 자메이카는 95년, 콜롬비아는 80년, 과테말라와 사모아는 75년을 저작권 보호 기간으로 적용하고 있습니다. 따라서 해당 국가에서 이 작품은 퍼블릭 도메인이 아닐 수 있으며, 저작권 상호주의 또한 적용되지 않을 수 있습니다.

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}}.
