"Star atlas. Four maps of the starry sky up to declination 50°S, containing all stars up to 5.5 magnitude."
This was an extremely successful star atlas created by Aleksandr Aleksandrovich Mikhailov (26-04-1888 - 29-09-1983).
The first edition was published in 1913, so even before the Russian Revolution.
My copy is a third, revised edition of 1958 and published by the Academy of Sciences of the USSR.
The love for the starry skies is stronger than politics. I hope.
