John J Arnold
John J. Arnold was a commercial artist specialising in transport. He is known to have contributed illustrations to Look and Learn and Speed & Power magazines, and almost certainly contributed to other IPC Transport titles. His work for Look and Learn often involved beautifully rendered line & wash diagrams of cars, such as in his 'Classic Cars' series (1974) and 'Novelties of Mobility' (1974-75).

He also illustrated other forms of transport, including sailing ships and paddle steamers.
