in p>1851, Procter & Gamble (P&; G) William Porter, the founder, found that the workers in charge of shipping goods always drew marks such as stars and the moon on the boxes of P&G products to distinguish them from other goods. As a result, P&G Company formed a trademark with the theme of the moon and stars in 1882, and set the number of stars as 13, indicating 13 states at that time.
