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 file is a Ukrainian or Ukrainian SSR work and it is presently in the public domainin Ukraine, because it was published before January 1, 1955, and the creator (if known) died before that date (details).
A Ukrainian or Ukrainian SSR work that is in the public domain in Ukraine according to this rule is in the public domain in the U.S. only if it was in the public domain in Ukraine before January 1, 1996, e.g. if it was published before January 1, 1946and the creator died before this date, and no copyright was registered in the U.S. (This is the combined effect of the retroactive [1], Ukraine's joining the Berne Convention in 1996, and of 17 USC 104A with its critical date of January 1, 1996.)
