Vladimir Tatlin and his apprentices constructing the model of Tatlin’s Tower, a monument to the Third International.

Tower (400m at height) should be erected in Petrograd as a symbol of the October Revolution’s victory. The framework consist of four geometric structures made of steel and glass that rotate at different speed. Every structure has its own purpose: first contains legislative body, second - executive, third by information centre and its maintenance (radio, telegraph and etc) and the forth - unknown. Tatlin made several projects of it.

As with Letatlin, Tatlin understood that this construction could not  work due to technical development of the age.
