In this paper, Robert Phiddian explores four pragmatic issues involved in writing a biography of Australian cartoonist and illustrator, Bruce Petty. When your subject has published at least weekly and often daily since 1963 (apart from annual leave and a brief hiatus of 2 months in 1976), your problem is one of profusion. When your subject has also made a dozen animated features, hundreds of prints, several sculptures, and half a dozen books, your problem with profusion is not exactly dissipating. When your subject has led a personal life that in many ways exemplifies the social changes in Australia in a period spanning the Depression to the present, and is happy enough to talk about them, sanity demands that you view profusion is a realm of happy opportunity.
