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.
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.
