Haynes guide to Wallace and Gromit
Haynes, best known for publishing car repair manuals, has branched out into the wacky world of much-loved TV characters Wallace and Gromit.
Fans of the animated duo can now explore the innermost workings of their inventions in the Wallace & Gromit: Cracking Contraptions Manual.
The book has been published to coincide with the start of the new Wallace & Gromit TV series.
It interweaves meticulously researched technical descriptions with fantastically detailed cutaway drawings and photographs - all presented in classic Haynes manual style.
The manual reveals how iconic machines, such as the Techno Trousers, Knit-O-Matic, Moon Rocket and Motorcycle with Sidecar, actually work.
Speaking at the launch at the At-Bristol science museum, Wallace & Gromit creator Nick Park said: "I have always been aware of Haynes Manuals, I guess my first memory would be that my older brother had one for his Austin Riley.
"They're wonderfully practical, it's a shame that Wallace didn't have this edition a few years ago actually, it certainly might have made Gromit's life a bit less stressful."
The project has also inspired Wallace to come up with a cracking new contraption - the Edit-O-Matic - an ingenious machine for editing publishers' proofs.
As Wallace explains in the book's Foreword, their latest invention "is bound to bring this publishing game into the modern age".
It is illustrated by Graham Bleathman who is well known for his drawings for the cult Gerry Anderson TV shows Thunderbirds, Captain Scarlet and Stingray.
