Extras include an interesting Q&A with Jules Feiffer. Here's a sample:
- Q: What did you enjoy about working with Norman Juster on The Phantom Tollbooth?
- A: First of all, we were roommates, so it was just part of the ongoing relationship of two people eager to establish themselves in some sort of career. A lot of other things were going on. You know, while we were collaborating on the book, we were actually exchanging girlfriends.
And, there's a bookend Q&A with Norman Juster as well.
