Public domainPublic domainfalsefalse
The author of this image from Switzerland is unknown, and the image was published at least 70 years ago. It is therefore in the public domain in Switzerland by virtue of Art. 31 of the Swiss Copyright Act.
Note that this applies only if a reliable source is cited to indicate that the author is not publicly known; just not knowing who the author is is not enough to qualify the image as public domain. This image may not be in the public domain in countries other than Switzerland.
This image is in the public domain in countries and areas where the copyright term for anonymous or pseudonymous works is 70 years from the year of first publication or less, for example in the European Union.
Please give also an explanation why the work is in the public domain in its source country and in the United States. If this work was published after 1928 and it was not in the public domain in its source country on the URAA date (January 1, 1996 for most countries), use {{Not-PD-US-URAA}} in addition to this template.
For files in the public domain in the EU, please use {{PD-anon-70-EU}} (see the documentation).
