Although Mala mentions that Vladek has read Prisoner on the Hell Planets, it was not necessary for Spiegelman to include a reprint of this early comic in the middle of Maus. Why do you think he chose to do so?

The short interruption of "Prisoner on the Hell Planet" comprises an additional narrative voice in Maus, making a total of four voices (past, present, meta, and "prisoner"). The comic represents an entirely new and radically different artistic style than the simple and subdued style present throughout the rest of the book. The characters have distinctly human faces, and the drawings are marked by sharp angles, altered perspectives, and often surreal and grotesque human forms. But while the artistic style differs, it shares with Maus the theme of guilt.
