The Spotlight ON series specializes in color profiles of a given subject. In this case it is the Mirage III and Mirage 5 series of aircraft.
The book starts with a two pages description (landscape format) the characteristics of the aircraft and operational history of it. It is not meant to be exhaustive; it is just a primer as the real reason for this book are the fantastic 42 color profiles of the Mirage in service with different air forces.
With an aircraft that has seen such an extensive service -and combat- it is not possible to cover every single camouflage scheme worn by them. As such the book selects a representative sample of mainstream and one-off schemes, like retirement schemes and such.
