I'm not sure I can name a kind of story that wouldn't work in comics form. It's words and images, and we've been telling all kinds of stories with that combination since theatre was invented thousands of years ago.

I'd forgotten how challenging comics can be until I started working on Ropes. Yes, you're restricted by the boundaries of the page, but we all work within technical limitations of some kind.

I can't blame anyone for being pessimistic when they look around, after all the blood spilled and energy spent to gain ground for working people in the past, and see it all happening again. I wasn't pointing a finger when I wrote the book, but sometimes the message is there even when you aren't actively trying to be the messenger.

For all the idealism that propels him through the story, if you read between the lines you may see that at a moment which he considers a defining point in his life as an activist, he's also set the stage for potential ugliness down the road.

One of the things I really worry about is that if you don't see middle class wage growth, if you don't see the economy in certain areas of the country, the middle part of the country, starting to come back in the same way that it's doing especially well, let's say, in California or New York, then people are going to become politically frustrated.

But knowing that the world had come full circle to our Depression story didn't change the way we worked on it, or encourage us to change our thrust. I want people to be able to pick up this book in the future no matter what's going on in the world, and appreciate it on its own merits, not for any perceived winks at the headlines.

There's a certain pressure you put on yourself to use the comics page to full advantage that can focus your mind to a pinpoint, and when the juices are flowing, that's incredibly exciting. When you've managed to fit a complex set of actions or a complicated emotional passage into a single page there's the sense of satisfaction that I suspect a sculptor gets from chipping away at a piece of stone and ending up with a fully-realized work of art.
