"Do you know that it is not allowed to laugh in hell, and if you break this law, you will get rigorous punishment? Do you wonder if the little devil can visit the sky? Or maybe you would like to know how the Guardian Angel can help you? If you already know the cheerful Angel and the tricky Little Devils from the books of the priest Malinski, you are already in love with them... Or maybe you don't know? Then, a whole lot of fun is ahead of you!"--Translated from p. [4] of cover.
