The first-known image of Cassius Clay on something resembling a trading card was published as part of a four-photo panel in a Swedish magazine. Depicting Clay as an Olympic boxing champion, the future Greatest of All Time was joined on the page by speedwalker John Ljunggren, Wilma Rudolph and Danish soccer player Harald Nielsen. While the panel was intended to be put into a two-ring binder, collectors have chosen to cut the panel into cards, making this hand-cut gem the rookie card of Muhammad Ali, perhaps the most famous celebrity in the history of the world. Dating to Clay's Olympic medal victory in Rome, the card includes some biographical information on the reverse. Well-centered, clean, and sharp, with just a tiny bid of moderate toning. A monumentally important card.
