The world’s largest book has been published. It’s a book of photographs of the kingdom of Bhutan. “Opening to 1.5 by 2 metres and weighing more than 60 kilograms, the book is so big it needs its own Sherpa. The price? A cool $10,000 (U.S.), 17 times what the average Bhutanese earns in a year, although the books only cost $1,000 each to produce, with the remaining $9,000 benefiting the Bhutanese ministry of education as a charitable donation.”
