The logo of Procter & Gamble means the combination of the head of the old man and the stars. William Porter found that the workers in charge of shipping always draw stars and moons on the boxes of Procter & Gamble products to distinguish them from other goods. Because Procter & Gamble formed a trademark with the theme of the moon and stars in 1882, and set the number of stars as 13, which meant 13 continents at that time. Trademark p&; The name of G was taken by two founders, Prost and Gaim, and the name used the first letters P and G of their names, so the name of the company was called PG Company.
