 In the times of Khrushchov (First Secretary of the Central Committee of the Communist Party of the Soviet Union from 1953 to 1964) and of Brezhnev (in power 1966–1982), however, the pressure lightened.Mid- and late-Soviet children's books by Eduard Uspensky, Yuri Entin, Viktor Dragunsky bear no signs of propaganda.In the 1970s many of these books, as well as stories by foreign children's writers, were adapted into animation.
