Note that this tag cannot be used on all signatures, as not all signatures are copyright-free.
The Russian Federation (early Soviet Russia, RSFSR) is the historical heir but not legal successor of the Russian Empire, and the Russian Empire was not party to the Berne Convention (it was not country of Union for the protection of the rights of authors in their literary and artistic works), so according to article 5 of the Convention this work has no country of origin except:
in the case of cinematographic work the maker of which has his headquarters or his habitual residence in a country of the Union, the country of origin shall be that country,
in the case of architecture erected in a country of the Union or other artistic works incorporated in a building or other structure located in a country of the Union, the country of origin shall be that country,
in the case of other works if the author is a national of a country of the Union¹, the country of origin shall be that country.
¹ - Author who is not a national of a country of the Union but who has his habitual residence in a country of the Union, be assimilated to national of that country.
