Ferrero SpA's Duplo, Fererro Rocher, Nutella, Mon Cheri and Pocket Coffee chocolate products are arranged for a photograph in Milan, Italy, on Thursday, Nov. 19, 2009. Michele Ferrero sold his first batch of Nutella spread in 1964. Four decades later, Italy's richest man must decide whether his company fast-tracks overseas growth by starting an auction for Cadbury Plc, or sticks to its recipe of homegrown sweets.
