Explanation:

It is well known that in Photographs and Paintings, Stalin would "erase", People in his regime that were either considered his Enemies/Rivals which due to his paranoid suspicions during the Great Purge that occurred from 1936-1938. Such removal of Political Enemies could happen from either something as major as Sympathizing or Working with a rival like Leon Trotsky, Or a simple disagreement of policy or idea. But never the less Stalin erased many of his Commissars and Government officials that were in photo's or painting's with him as to give off a portrayal that Stalin was "Infallible" and could do no wrong , Reinforcing his Cult of Personality. This practice continued well after Stalin's death, Continuing as far as the fall of the Union in 1991.
