0,10 — The Last Futurist Exhibition of Paintings

In wartime Petrograd, Kazimir Malevich unveiled Suprematism: thirty-nine paintings of pure geometric form, with the Black Square hung high across a corner of the room, the place icons occupy in a Russian home. Vladimir Tatlin showed his counter-reliefs in the same exhibition, founding the rival line that became Constructivism.

Two of abstraction's founding programs, Suprematism and Constructivism, entered the world in one room, in open argument with each other.
