That statue was never made! Well, the palace itself was never finished as well, it was interrupted by the war and the construction was cannibalised for materials.
In any case to build this Lazar Kaganovitch (S.O.B. big time!) had ordered the demolition of the Cathedral of Christ the Saviour in 1931 to put in the Palace in its place. Putin ordered the the building demolished and the Cathedral rebuilt in its former location, inaugurated in 2000. Boris Yeltsin is buried there!
