Paul (Harv) Harvey has that infuriating but awe-inspiring knack of being able to draw instantly recognisable caricatures of some of our greatest sports stars.

To call him a caricaturist, however, is to sell him short because he adapts his style to suit the medium and the occasion, whether its illustrating childrens books, conducting corporate presentations, designing company logos or painstakingly creating Brownlow certificates.

Harv doesnt draw in some rarefied vacuum. He has a vast knowledge of football history, and he understands and acknowledges the debt of those great cartoonists who came before him.

Nick Hunter has written more than 50 books for young people.

He has a degree in modern history and specializes in writing about history and social studies.

Before becoming an author, Nick worked in children's publishing for many years. He lives in Oxford, UK with his wife and two sons.

Paul's books cover a wide range of subjects, from whether the Romans ate crisps to how to build the world's best skatepark, but he writes mostly about sport.

Whether you are interested in swimming or cycling, snowboarding, surfing or another sport, Paul has probably written something that will inspire you to get out and give it a try.

Paul writes in a shack by the beach, which he shares with his one-eyed surf dog, Daisy.
