I've scanned this image in from the October 1974 Super Sports edition of Esquire magazine, which I've kept all these years, mostly for this startling actual size photo of Muhammad Ali's massive right first. It's coming up the correct size on my screen, at more than 5 3/4 inches, or more than 14.5cm, into which my own puny effort of almost 4 1/2 inches simply disappears. But the reader may need to click on the image to see it in its proper size (and compare their own fist). The same issue of Esquire contained an adaptation from the late Wilfrid Sheed's 1975 portrait of Ali (see the first page below). Sheed was quite right to support Ali's belief that he was the most famous man in the world at that time. (Though an English-born American writer, Sheed was the son of a second generation Australian, Frank Sheed.)

Ali at Heathrow Airport in late November 1974, at the time I met him at the New Victoria Theatre in London.
