Malevich's cover lithographs are amongst the few only known colour lithographs attributed to him. They illustrate a series of lectures given by Punin in the summer of 1919 condemning decadent and romantic art of the past and calling for a new dynamic artistic culture of the future. The prints illustrate Malevich's interest in juxtaposing suprematist shapes to give his compositions energy and movement. They owe much to experiments he conducted at Unovis in 1919 where Lissitzky was concurrently working on his Proun compositions.
