"Want to Know Everything" book set

A unique opportunity to acquire a very interesting large-format set of Soviet-era educational books from the series "I Want to Know Everything" (1980-1985). The books are something between thin, simplified encyclopedias and engaging stories for children. Large, beautiful illustrations, interesting explanatory descriptions. A boy interested in airplanes, ships, buildings, trees will definitely be thrilled. The pages of the books are in excellent condition, the covers have become slightly worn over time, but it is evident that the books were used carefully.
