Artists have never worked with the model – just with the painting. What you [G. R. Swenson, the interviewer] are really saying is that an artist like Cézanne transforms what we think the painting ought to look like into something he thinks it ought to look like. He's working with paint, not nature; he's making a painting, he's forming. I think my work is different from comic strips – but I wouldn't call it transformation; I don't think that whatever is meant by it is important to art. What I do is form, whereas the comic strip is not formed in the sense I'm using the word; the comics have shapes but there has been no effort to make them intensely unified. The purpose is different, one intends to depict and I intend to unify.
