Kiev-Druk (i.e. Kiev-Printing) was a major typographic firm in the Ukrainian Soviet Socialist Republic (Ukrainian SSR) from the 1920s into the 1930s. It turned out printed materials including books and posters. While its offices were located at 19 Lenin Boulevard in Kiev, the printer also had satellite departments around the Ukrainian SSR.
