“This is the first poster in which graphic language acquires independence from painting. ln this, it was quite unlike the poster for the 1st Bienal, when the author was a Constructivist artist and also an occasional designer,’ here, the author was a designer and a sometime Constructivist artist. Forms succeed each other in a mathematical progression-pairs of triangles make up squares and their diagonaIs have the same dimension as the following square; the texts are carefully laid out so that the whole poster follows one single compositional principIe.”.
