Postage stamps are an attractive vehicle for presenting mathematics and its development. For many years the author has presented illustrated lectures entitled "Stamping Through Mathematics" to school and college groups and to mathematical clubs and societies, and has written a regular "Stamp Corner" for the Mathematical Intelligencer. The book contains almost four hundred postage stamps relating to mathematics, ranging from the earliest forms of counting to the modern computer age. Featured are many of the mathematicians who contributed to this story - influential figures, such as Pythagoras, Archimedes, Newton and Einstein - and some of the areas whose study aided this development - such as navigation, astronomy and art. The stamps appear enlarged and in full colour with full historical commentary, and are listed at the end of the book.
