The International Tennis Federation has launched a book celebrating the sport's participation at the Olympics, featuring photos of several current stars with notes about their childhood dreams.
The book was presented Wednesday at Wimbledon, where the tennis tournament for the London Games will be held.
The book is called "Aspire Inspire: Celebrating Tennis at the Olympics 2012," and includes pictures of players such as Rafael Nadal, Roger Federer and Novak Djokovic showing photos of themselves as children and listing their sporting heroes.
The book also includes letters from some of the athletes the players picked,Â including one from Usain Bolt to Francesca Schiavone and a note from Alberto Tomba to Djokovic.
The 140-page book will not be for sale to the public, but an online version will be posted on the ITF website.
