From 1923 to 1928 Rodchenko collaborated closely with Mayakovsky (of whom he took several portraits) on the design and layout of LEF and "Novy LEF", the publications of Constructivist artists. Many of his photographs appeared in or were used as covers for these and other journals. His images eliminated unnecessary detail, emphasized dynamic diagonal composition, and were concerned with the placement and movement of objects in space. During this period, he and Stepanova painted the well-known panels of the Mosselprom building in Moscow. Their daughter, Varvara Rodchenko, was born in 1925.
