About the book: 1966 / In this extraordinary educational book, the young reader will meet the restless inventors Pugovkin and Romashkin. My bosom friends now have a lot of acquaintances who are just as inquisitive, observant, and savvy, who make many useful and entertaining things from the simplest materials.
