LT UN-9 was the abbreviation for the Printing House No. 9 of the Publishing and Printing Department of the Executive Committee of the Leningrad City Council. Research suggests the LT naming convention began during World War II and it was accorded to at least ten printers in Leningrad. For example, Printing House No. 1 (LT UN-1) was located at 57 Fontanka Embankment.

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.
