From left to right: Marshal Kliment Voroshilov, Chairman of the council of People’s Commissars Vyacheslav Molotov, General Secretary of the PCUS Joseph Stalin pose at the shore of the the Moscow -Volga Canal, in 1937 in this manipulated picture. In the original picture Nikolai Yezhov was standing on the right. Yezhov was the senior figure in the NKVD (the Soviet secret police) under Joseph Stalin during the period of the Great Purge. After Yezhov was tried and executed his likeness was removed from this image between 1939-1991. The Moscow Canal (Russian: ?????? ?????? ???????), named the Moscow-Volga Canal until the year 1947, is a canal that connects the Moskva River with the main transportation artery of European Russia, the Volga River. It is located in Moscow itself and in the Moscow Oblast. It was constructed from the year 1932 to the year 1937 by Gulag prisoners during the early to mid Stalin era.
