This book complied by Lissitzky's widow, is the first full-length, fully-documented study of the artist to appear. It opens with a long biographical section, largely based on his letters, which throw a great deal of light on his aims and on the circles in which he moved. This is followed by a series of plates in which every field of his activity is handsomely represented, and by two valuable collections of literary documents: theoretical writings by Lissitzky himself, and accounts of him by contemporaries and by later critics.
