Public domainPublic domainfalsefalse
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.
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.
This Swedish photograph is in the public domain in Sweden because one of the following applies:
The photograph does not reach the Swedish threshold of originality (common for snapshots and journalistic photos) and was created before 1 January 1974 (SFS 1960:729, § 49a).
The photograph was published anonymously before 1 January 1954 and the author did not reveal their identity during the following 70 years (SFS 1960:729, § 44).
For photos in the first category created before 1969, also {{PD-1996}} usually applies. For photos in the second category published before 1929, also {{PD-US-expired}} usually applies.
If the photographer died before 1954, {{PD-old-70}} should be used instead of this tag. If the author died before 1926, also {{PD-1996}} usually applies.
You must also include a United States public domain tag to indicate why this work is in the public domain in the United States.
Note that a few countries have copyright terms longer than 70 years: Mexico has 100 years, Jamaica has 95 years, Colombia has 80 years, and Guatemala and Samoa have 75 years. This image may not be in the public domain in these countries, which moreover do not implement the rule of the shorter term. Honduras has a general copyright term of 75 years, but it does implement the rule of the shorter term. Copyright may extend on works created by French who died for France in World War II (more information), Russians who served in the Eastern Front of World War II (known as the Great Patriotic War in Russia) and posthumously rehabilitated victims of Soviet repressions (more information).
