Query: monumental classic

I can't argue with a classic, such as this. For its time, this book must have been monumental (I'm too young to know) but even in these days the book still stands as an icon. If one doesn't know much about communism, then not everything will be reaped from the reading. However, someone with understanding (1st or 3rd hand) of communism, then this book will provide a great parody on the faults of communism.
