Art Spiegelman on Maus.
There's a write-up at the NYT about MetaMaus, which is being released for the 25th anniversary of Maus' publication.
This was my favorite bit:
Twenty-five years after its original publication, “Maus” continues to provoke. Mr. Spiegelman recalls an incident in Germany in 1987, when a reporter barked at him, “Don’t you think that a comic book about the Holocaust is in bad taste?”
The author responded, “No, I thought Auschwitz was in bad taste.”
It's too bad that he took issue with it getting a YA award—he felt that winning the award suggested it was "immature"—but, as we've seen recently, there are plenty of people who don't differentiate between children's, middle grade, and young adult, so maybe that's what was going on with that.
