A polo player himself, Horace A. Laffaye is on the Board of Directors of the Museum of Polo. His writings on the game include two books and many articles in magazines in America, Argentina and England.

This work consolidates information about the history and tradition of polo that was previously contained in thousands of diverse sources. It provides an important reference tool for students and fans of the game and helps to preserve the sport's history while making it much more accessible.

More than 10,000 entries range from Abbot to Zwartberg, providing information about artists, authors and their writings, breeders, clubs, history, personalities, players, ponies, tournaments, an explanation of the rules of the game and a myriad of other topics. The book contains several tables and more than 100 illustrations, including drawings, photographs, paintings and portraits. Stephen A. Orthwein, chairman of the Museum of Polo and Hall of Fame and a past-chairman of the United States Polo Association, contributes a substantial foreword.
