Once in 1932, the Order of People's Commissars had banned all art associations and groups, but the only official Union of Artists to somehow distinguish between artists in a monotonous mass of steel to provide the Moscow and Leningrad schools, with more of Leningrad, as it included masters, dare to depart from the social realism is far more than Moscow. Samokhvalov, Pakhomov, Kazan, Rusakov, Kupervasser, Vedernikov, Cremer, Stipa, Lebedev, Basmanov, Sterligov - these brilliant names are the pride of this school, they gladly include in their collection as admirers of social realism, and fans left art. I'm sure someone forgot because I sit in the country, away from his library, I hope, I will add.
Among the Sixties in St. Petersburg can be identified arefevskuyu group, but, actually, that's another story.
