Αυτό το έργο είναι κοινό κτήμα στη χώρα προέλευσής του και άλλες χώρες και περιοχές όπου η διάρκεια πνευματικών δικαιωμάτων είναι όσο η ζωή του δημιουργού και μέχρι 70 χρόνια μετά ή λιγότερο.

This image may not be in the public domain in these countries, which moreover do not 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).
