You do not need to be a professional in the banknote business to find this superb book a fascinating read. Klaus Bender has researched this secretive industry and discovered a number of skeletons in its cupboard. While this is interesting, for me the greatest fascination was to learn of the developments, mainly after WW2, driven by entrepreneurs of exceptional ability and drive. They created wealthy, worldwide businesses based on unique technology in the areas printing machinery, specialist printing inks, and banknote printing.
Apart from being a super read, this book should be of serious interest to the business schools in the context of case study learning.
