How long is the world’s longest mustache? Who is the oldest person to win an Oscar? And how much did the world’s most expensive coin cost?
The answers to these questions, and hundreds of others, can of course be found in Guinness World Records, the book that is a record in and of itself. With over 100 million copies sold since its first edition in 1955, it is the world's most-sold licensed book. Today it is published in 25 languages in more than 100 countries.
