Tintin in America: Outside of Hergé and some cameo appearances of his colleagues (such as the last piece of trivia), Al Capone is the only real person to appear in any of the Tintin albums. In the original black-and-white edition, Capone had a scarf covering his face, but in the 1945 color edition, Hergé chose to remove the scarf and draw all of his face.

There was one other real person in the book, but only in the black-and-white edition: the actress Mark Pickford is at the ceremonial dinner.
