For the first time, three stories by the classic of Russian children's literature Lev Kassil: “Kunduit and Shvambraniya”, “My dear boys” and “Be prepared, Your Highness!” in one volume. In 1915, two brothers Lelya and Oska came up with the fabulous country of Shvambrania. The events that happened in it mirrored what was happening in Russia - war, revolution, the formation of Soviet power. Even before the war, school teacher Arseny Gai and his students - Kapiton, Valera and Timson - came up with a fairy tale about the magical country of Sinegoria, where brave people live. When the war began and Guy went to the front, the guys organized a detachment of “Sinegorsk residents” to bring to life the motto of the fairy tale he had invented - “Courage, loyalty, work, victory.” In 1964, the heir to the Spartak children’s camp came to rest Prince of Jungakhora - a fictional kingdom of Southeast Asia. The book is equipped with a biography of the author and illustrations dedicated to the life of pre-revolutionary high school students and Soviet schoolchildren before the war and in the early sixties. The publishing layout of the book is saved in PDF A4 format.
