The artist's name on the poster is not indicated. By assigning Artist Unknown to a poster it also could mean the artist used a chop mark whereby no signature is seen thus rendering the artist's identity anonymous.
Mosoblpoligraf was a regional, state-owned printing trust created in the mid-1920s during the period when the Soviet Union was consolidating its best and most productive printers. The 5th Lithography Workshop, 12th Lithography Workshop, 16th Lithography Workshop and the 26th Lithography Workshop were all Moscow-based printers under the Mosoblpoligraf banner.
The history of IzoGiz begins with the formation of Ogiz, the Association of the State Book and Magazine Publishers. In 1930, the Sovnarkom of the Russian Socialist Federative Soviet Republic established Ogiz to centralize publishing under a monopoly in order to eliminate duplication of printed material, to streamline and control publishing production and its output, and to create a base for marketing books, training and technical manuals. In 1931, the Central Committee of the USSR ordered certain publications be separated from Ogiz. The separation principally affected technical manuals and propaganda material issued by the publisher. For example, posters, art magazines and artistic books were placed under Izogiz (Izobrazitel'noe iskusstvo), the fine arts section of Ogiz. In 1963, Izogiz was merged with the publishing house, "Soviet Artist" (Sovetskii khudozhnik).
