My grandmother had one of the first editions and it was clearly meant for people that were limited to the entry level school education, if that much. The book was basically printed in large letters, the sentences was generally short and the storyline was as flat as it was obvious. It's a "working man" novel about "working man" subjects written in a "working man" language. Propaganda all the way. It's certainly worth a read to get an idea of what the early Soviet literature was like.
