Cartoons and Exile?

In the book A Survivor's Tale, by Art Spiegelman one is radically taken away from all the conventional and customary memoir books of the holocaust; Spiegelman's cats, mice and pigs are able to effectively recreate a horrendous time in history that was full of struggle, difficulty, solitude, and physical and emotional exile for all the innocent people that had to go through it.
At the same time, Spiegelman's tale presents and depicts a different type of exile, an exile that is lived by those who fortunately did not have to go through the traumatizing experience of the holocaust but do have families who did, and can not seem to relate to the long time effects of such devastating and shameful time in history.
Perhaps the most outstanding part of the book is the parallel between trying to write, draw and illustrate a striking historical time and relating it to his family, and his already deteriorated relationship with his dad. As the author gets, deeper into the story he clearly gives out his change of feelings and reduces his distance and obvious exile between him and his dad. However, he is never able to fully destroy the bar between him and his dad, between him and his family's history.
