It seems to me that this id book was given to Alexandru Kuzmichy Beleevskomu that allows him to service objects in the city. It states that he was studying in "Estonglavenergo" and is qualified "2nd level Stropalshik" (I am not sure what that means).
It could be a form of certificate of complition.
This is a civilian id that would allow him to work for the city.
This seems to be a certificate from NKVD stating that a woman named Kornilova Nina Konstantinovna is not under supervision (I dont know if there is a better way to translate uchet) of People Komissariat of Internal Affairs.
Can we have a closer look.
It says that the recepient was awarded Medal for Labor Merit, but the doc itself has picture of Honored Miner badge.
The doc is signed by the Minister of Mining Industry Zasadko. He was quite famous person, there's huge mining factory in Donbass, Ukraine named after him.
Could this be substitute for the official award book?
