In 1901 Connie Mack and his Philadelphia Athletics became one of the original founders of the American League. In 1902 New York Giants Manager John McGraw dismissed the A's with contempt, by calling them "The White Elephants." He meant to imply that Mack shouldn't be allowed to spend money without supervision. Well, Connie Mack took up the gauntlet and defiantly adopted the White Elephant as the team insignia. That year, 1902, the A's won the American League pennant -- much to the unvoiced chagrin of John McGraw.
1920 - The White Elephant logo was good to the Philadelphia Athletics -- Pennants were won in 1902, 1905, 1910, 1911, 1913, 1914, 1929, 1930, and 1931, while the teams of 1910, 1911, 1913, 1929, and 1930 won the World Series.
