The Detgiz publishing and printing plant in Moscow was located at 49 Sushchevskii Rampart. While it focused on children's books, occasionally it printed political posters. Detgiz was founded in 1933 with the aid of Maxim Gorky, famed Russian author. His participation attracted literary talent, resulting in Soviet writers, artists and educators being dully employed by Detgiz. There were many departments within Detgiz such as fiction, science fiction, classical literature and preschool reading. The firm was also affiliated with the Moscow-based "House of Children's Books", a store where writers performed live readings of their books for children.
Iskusstvo was the Art Publishing House (A.K.A. Visual Arts Publishing) that was created in 1936 from Ogiz-Izogiz (State Art and Literature Publishing House). It disseminated books and journals dealing with graphic design and the fine arts, and it issued numerous posters. Since the Iskusstvo banner was part of the State Printing Works in Leningrad (St. Petersburg) and Moscow, its two main offices were located in those two cities.
