"This short book, intended for children of all ages, is perhaps the best–known work of El Lissitzky (1890–1941). Lissitzky was a Russian artist, architect, designer, typographer, and photographer who was active in the avante garde movement that flourished in Soviet Russia and in Germany, until the dominance of Soviet Realism by 1930 put a stop to its revolutionary activity. He directly influenced the typographical and display advertising innovations of the Bauhaus and 'de Stijl'. This book entirely integrates modern typographical effects, as Lissitzky intended, with his illustrations in the Suprematist style.
The original book About Two Squares was printed by letterpress, even the slanted text and illustrations. It was first produced ('constructed') in 1920 at the Soviet art institute UNOVIS in Vitebsk, and around April 1922 printed by Sycthian Press, Berlin, by Haberland Printers, Leipzig, in paperback, with 50 hardbound copies autographed and numbered, as the copyright page states."
