Back in 1917, American
From the Mental Floss synopsis:
The slides capture everything from soldiers wearing gas masks near bunkers to ruined buildings in Moscow. Orlov told Radio Free Europe/Radio Liberty that the slides "were hand-colored by what must have been one of the very best photo-finishing businesses in the U.S. I am still hoping to find out who did such a wonderful job with them."
[In addition] the collection also features images that Rahill snapped as he was evacuated from Russia through China and Japan.

*Short version: The Russian Revolution was when the Bolshevicks (later more commonly referred to as Communists) took over the country from the former Imperialist Royals/government, ending the reign (and lives**) of the Romanov family led by Nicholas II.
**What about Anastasia?!
