A bit more of a preview of the item about CBS Sunday Morning - but probably not the way Charles Kuralt would have given his love to the story.

AUTOBIOGRAPHY:  Mark Twain
He's been called the greatest American writer of all time. His bestselling novel, "The Adventures of Huckleberry Finn" - the book, Ernest Hemingway wrote, from which "all American literature comes" - is still read by schoolchildren around the world.

At the turn of the last century, Twain was, in his own words, "the most conspicuous person on the planet," - known throughout the world for his white suit, his many books, and his side-splitting lectures.

But his latest accomplishment may be his most amazing . . . publishing a NEW book, his "Autobiography," one hundred years after his death.

CBS News correspondent Jeff Glor will take the measure of Mark Twain, with the help of the Twain Project, in Berkeley, Calif.; the J. Pierpont Morgan Museum in New York; and comedian Lewis Black.
