* WhatCouldHaveBeen:
** Tragically in-universe as there's an arc in Volume I of Art trying to procure his mother's diaries from his father only to be dist. Just imagine how ''Maus'' would have been with Anja's diaries if Vladek hadn't destroyed them.
** In addition, Art asks his father about the letters of his French friend (a frog) from the camps when they corresponded after the war. Vladek regretfully says he destroyed those too.
** Art mentioned he ''turned down'' offers to have the comic turned into an animated movie - it's even alluded to in the second volume.
** It was originally going to be one volume, but Spiegelman wanted to get it out ahead of the release of ''WesternAnimation/AnAmericanTail'', a movie also featuring Jewish mice. Spiegelman has publicly accused the directors Steven Spielberg and Don Bluth of plagiarism, though beyond using cats and mice as a metaphor for racism the similarities between the two works end there.
