Kh.M. is the abbreviation for the State Free Artists' Studios (Khudozhestvenye Masterskie), a poster arts cooperative of Izogiz publishers. In 1930, Kh.M studios existed only in Moscow and Leningrad and it was turning out propaganda for the First Five-Year Plan and for the efforts of collectivization. The earliest poster works created by the cooperative thus reflect these two themes.
Izogiz was the fine arts section of Ogiz publishing. In 1963, Izogiz was re-named Sovetskii khudozhnik, "Soviet Artist".
