Cassius Clay signed and inscribed “I am the Greatest” Black is Best Book

One of the most ferocious fighters of all time and to many “The Greatest”. Ali aka formerly Cassius Clay is what America would call a true Patriot and a American Hero. The book cover is in poor/fair to condition with the book itself being closer to fair/mint. Despite the cover/book wear the auto is in Excellent Condition and reads as follows: “Cassius Clay I am the Greatest”.
