This interesting little book could more accuratelybe described as a pictorial record of police car liveries. Beyond an introductory section - summarising the history of British police forces - it does not cover the development of the police car per se, only the evolution of police car liveries in England and Wales, with an emphasis on the later, high-visibility eras. This it does very well, with an interesting selection of well-reproduced colour photographs (typically 2-3 per page) and a lively if concise commentary. I had hoped for more pre-high visability photos but was not unduly disappointed, having already purchased Malcolm Bobbitt's excellent Police Cars book - for which this is a useful companion, but certainly not a substitute. The author does blot his copybook slightly in the way that he expresses his opinion of the current 'national' police car livery and the people who designed it. That aside, provided you know what it is - and is not - - it is a worthwhile purchase at Amazon's discounted price..
