Cartoons were very conservative. The country was very conservative. Although the liberals were allegedly in charge for a long time, there was a very acceptable balance what people would talk about in public. And I wanted to stretch those and move further out. And as the civil rights movement began, I started doing cartoons on that and on sit-ins and I was, along with Bill Mauldin, a great cartoonist out of World War II, arguably one of two white cartoonists doing this kind of work, Bill and me.

I was doing cartoons and mocking white liberals, mocking the attitude of government who said to go slow, while intending to do absolutely nothing for black people, then called Negroes. And I had a lot of fun and I expressed a lot of anger. That was a thing that was important to know at that time. As I was emerging into more and more into politics that I was angry.

When I am working a book, I go through my library and take a look through some of the great cartoonists of the past, like Cliff Sterrett, who did "Polly and Her Pals," or Winsor McCay who did "A Little Nemo in Slumberland," and Herriman - and I just looked through these guys and looked for somebody to steal. You know, looked for who I could swipe, or turn into - who's work I will turn into my work. And I still use, after all these years, these artists as inspirations. So, here in my eighties, I go back to when I was eight for my inspiration.

I've had enormous luck and enormous pleasure in working in such forms as movies and plays that I loved when I was a kid and I just - because I could always write dialogue, because I always had a sense of how people spoke. And because I had a strong narrative sense; growing up and loving stories, loving novels, I just seem to know how to tell a story and I read a lot, I went to a lot of movies, I went to a lot of plays, and it rubbed off on me. And that's all. It just rubbed off on me.

That was exciting to be able to comment on civil rights. I mean, the civil rights movement that young people don't know about today, but Martin Luther King was considered by the establishment press in the early years of the sit-in movement as a dangerous man, and he was the equivalent at that time as Malcolm X. And he was told to stop his demonstrations; they were against the law and all of that. Now that he's sainted and sanctified we've forgotten.

When you do the kind of work I do, everything is challenging, but probably the most challenging thing is getting up in the morning and getting on with it because it's so easy to stay in bed and not get on with it.

I've been around a long time and I've found that these forms, whether it's the cartoon, or whether it's a play, or all these dying forms refuse to die. Something happens to rejuvenate them and it will certainly happen to the political cartoon. It will come back. But whether it's on the internet, or whether it's in some other form, however that works, whether it looks the way it looks now, or entirely different, I have no idea. And thank God I don't have to worry about it.
