Book excerpt: This book, with contributions from many of the world's leading polo journalists, profiles more than 30 of the most influential polo players from history. The players covered were selected for inclusion based on their overall impact on the game rather than their prowess on the field, although many covered are considered all-time greats. Each chapter covers an individual player, including early pioneers, those who played during the "golden era" (the years between World War I and World War II), superstars, game-changers, and great contemporaries. The book includes numerous photographs and a foreword by H.R.H. The Prince of Wales.
