It is not well-known that the noted palindromist Leigh Mercer made a number of false starts before creating the immortal A MAN, A PLAN, A CANAL--PANAMA! Fortunately, his charlady, aware of Mercer's fame, made a practice of saving his wastebasket scraps. These, found among her effects after her death, were recently auctioned off by Sotheby's for a handsome sum, and can now be revealed to the world of logology.
