The epistolary heritage of Ilya Ehrenburg is published for the first time and includes both letters scattered across hard-to-reach periodicals and published here for the first time. The fate of the writer was such that he found himself in the epicenter of the most significant events of his time, so letters arranged in chronology give an impressive panorama of wars and revolutions, the heyday of the art of the world avant-garde. At the same time, they contain unique material on the history of literature, covering various political eras.
