Neil Leifer has shot over 10,000 rolls of football photography during his lifetime, and The Golden Age of American Football contains an array of his best snaps. While Leifer is most known for his shot of Muhammad Ali towering over Sonny Liston, the photographer considers his football photos his best work. From Vince Lombardi's Green Bay Packers to the Miami Dolphin's 1972 perfect season to "The Greatest Game Ever Played," this book gives you a glimpse of football heroes like Johnny Unitas, Jim Brown, Joe Namath, and more.
