This book is basically a photo album of personal pictures taken by veterans and their friends during the war. As you can imagine, these photos vary in quality from very blurred to ok, plus there are a handful of official propaganda photos shot by the Whermacht which are the clearest.This book does not go into details of the various motorcycles used, the theatres they were used in or how they were viewed by the men who rode them. Each photo has a few lines of text which all sound very much the same after a few pages (e.g. 'This is a BMW R75', or 'This is a Zundapp', etc., although how the author can tell the difference and recognise the model of cycle from the blurred photos is beyond me!).The only think I did like about this book was it's brief explanation on the heating system used on some models of motor cycle and the diagrams used (obviously from the cycle's user manual).
