Mathematics, Magic & Mystery, an excellent magic book by Martin Gardner, yet a slow seller for us. I can only assume it's the title that stops customers purchasing. But those that do are in for a treat - the tricks inside are incredible, they're varied and what's more, you don't have to be good at Maths to understand or perform them.
It really is a great little book, with over a hundred routines and effects using cards, dice, ropes, handkerchiefs and various other common objects. Purchase this and you'll be doing some great magic that many others overlook.
