An exclusive design or a special edition can make almost any object into a luxury item. But there is only one item in each category that can call itself the most expensive in the world. The Barbie doll with a diamond dress or the unique office chair by a top designer. There is even the most expensive hamburger. This book doesn't forget the classics, of course: the priciest luxury car, the gold mobile phone and the one and only Rolls-Royce among wristwatches. The most expensive luxuries reveal a world full of oddities that sometimes make you smile, or else dream with yearning.
