As said inside the book. It is a common misconception that no one in their right mind can imagine or understand the holocaust.
Spiegelman disproves this in one of the most unsettling, gripping and genius drawing of cartoon characters. It deals with every single issue about the holocaust; survivors guilt, luck, logic, stereotypes, racism, anti-semitism, inhumane treatment by the Polish towards the Jews even after the war and so on.
Art Spiegelman is comepletely faultless in his delivery of this chillling tale, the comics serve their purpose and the over all personification and metaphor of the Jews works so amazingly convincingly.
A facinating point to note is that this is not entirely about the holocaust, but also its effects of Spiegelmans own life and is consistently cross referencing himself and his own feelings of guilt for no knowing what had happened to his mother and father.
I wholeheartedly believe this book is suitable for everyone as to teach that such acts of evil should never happen again.
