Muhammad Ali is one of the most remarkable personalities of our time and the greatest sportsman ever to walk the earth. To honor this living legend, this publisher has created a work that is indeed epic in scale and aiming to be as unique as the man himself. A worthy tribute to his life should reflect the scale of his achievements, and “GOAT – Greatest of All Time” sets out to meet that task. Four years in the making, and the most comprehensive study of Ali to date, GOAT has pages of archival and original photographs, graphic artwork, articles and essays – many of them previously unpublished – chronicle six decades of his life in stunning detail. To cap it all, the project takes place with the participation of Ali himself and those members of his inner circle who have been closest to him over the years: from managers and key cornermen to friends, family and children; from spiritual and other advisers to broadcasters, essayists and journalists.
