Rare activity book. Propaganda Among Children. 

This book was printed in 1939, shortly before the expansion of the USSR's territory. When Western Ukraine and Western Belarus were annexed to the USSR, this edition became outdated.
The series of activity books was prepared by the House of Entertaining Science, a forward-thinking children's museum in Leningrad known for its interactive exhibitions, which was active from 1935 to 1941. This particular book was compiled by Lev Uspenskii (1900-1978), a writer known for his popular science books and one of the museum's founders.
