James Brown is an illustrator and designer who, together with his wife Malissa, supplies an excellent range of cards and prints to us. This book features his signature illustration style with text by Richard Platt and through the course of the book explains some of the greatest discoveries and inventions and tells how they have changed, and continue to change, our world. Among the things that are included in the book are satellites, aviation, radio, printing and fireworks. Suitable for children 7+, but also worth a sneaky look by those of . . . more mature years who haven't got a clue about the mechanics of our world.
