This technical manual by L. Femer, published in 1930 at the height of Soviet industrialization, is a primary source on the mechanization of construction processes during the First Five-Year Plan. Issued by the specialized publishing body "Tekhnika upravleniya" under the Supreme Council of the National Economy (VSNKh) and its "Stroymechanizatsiya" trust, the book systematically addresses the organization and application of machinery on construction sites. Its primary significance for collectors and historians of art lies in its exceptional constructivist cover design. The bold, geometric, and functional aesthetic of the cover is emblematic of the Russian avant-garde's direct engagement with industrial and utilitarian themes. While not explicitly signed, the design is stylistically characteristic of the work of Varvara Stepanova (1894–1958)—a central figure of constructivism, renowned for her graphic design, book art, and ideological commitment to creating a new visual language for the new society. As such, this volume transcends its technical content to become a valuable artifact of 1920s-1930s Soviet design culture, where art was consciously applied to everyday objects, including scientific and industrial literature.
