THREE-WHEELERS A-Z: The Definitive Encyclopaedia of Three-Wheeled Vehicles From 1940 to Date has - I hope - every single three-wheeler made since 1940 – no fewer than 1,122 different types, including trikes, bubble cars, microcars, kit cars, invalid carriages, touring choppers, design exercises, tuk tuks, flying cars and amphibious vehicles - from AB1 to Zzipper.
Published by Quiller Print, it has 240 pages and over 1,600 illustrations – very many never seen before in print.
