Colvin served his cartooning apprenticeship as a contributor and then staff cartoonist of the NZEF Times during World War II. He was cartoonist at Wellington’s Evening Post for a decade from 1946. His later distinguished Fleet Street career included staff stints on the News Chronicle, the Daily Telegraph, the News of the World, the Daily Sketch, the Daily Express and the Sunday Express. He also drew newspaper strip cartoons and is probably best remembered for his 2,000 Modesty Blaise strips.
