A design binding of Amusements in Mathematics by Henry Ernest Dudeney. This is a famous and popular book of recreational mathematical puzzles, problems and curiosities.
This binding uses an origata binding structure, which felt appropriate as the binding is a bit of a mathematical puzzle in itself. The math aspect comes in even further in the use of the golden ratio to calculate the placement and size of all the different pieces in the binding structure. The vintage design and years of patina on the original dust cover were kept and incorporated into the new cover. The book is housed in a complementing solander box.
