Query: Wonderful potential, poor execution

The paperback copy of Nature's Chaos that I received a few days ago is a severe disappointment. The fault lies entirely with the quality of the reproductions of some of Porter's finest work. Overall contrast is poor while the colour contrast blocks many details. The colours are generally off and in some cases there are errors of registration.The original edition may have been better and the text is a revelation. But if this book interests you, spring the extra expense for some decent printing.
