Imprenta: Typolithography Workshop named for V.V. Vorovskii, Moscow — Типо-литография им. Воровского, Москва
The Typolithography Workshop named for V.V. Vorovskii was named in honor of Vatslav Vatslavovich Vorovskii (1871-1923) who was the head of Gosizdat (State Publishing House) from 1919 to 1920. After leaving Gosizdat, Vorovskii served as a diplomat for the Soviet Union. In 1923, he was assassinated in Lausanne, Switzerland. The printing house bearing his name was located in Moscow at 18 Dzerzhinskii Street, a thoroughfare that later was named Bolshaia Lubianka.
