The Brooklyn "B" dates back to the beginning of the 20th Century. The first incarnations were of the Old English variety, but a "B" similar to the one on the left appeared on the Bridegroom's uniforms in 1908.
In 1937, New York World-Telegram cartoonist Willard Mullin, named "Sports Cartoonist of the Century" by the National Cartoonists Society in 1971, caught a cab ride home from a Dodgers game. The taxi driver asked "How'd our bums do today?" An inspired Mullin decided to create a cartoon to represent "Dem Bums" and inked an unkempt version of Emmett R. Kelly, a circus clown (who was hired to entertain the crowds at Ebbets Field in 1957). The bum pictured to the left adorned the cover of the 1955 Dodgers Yearbook.
On Feb. 21, 1957, Walter O'Malley traded the Dodgers' minor league team in Fort Worth, Tex., for the Cubs' Los Angeles Angels in the Pacific Coast League, paving the way for the Dodgers to move to California. The Angels had two caps, one with an interlocking LA and another with the "L" and "A" side-by-side. O'Malley liked the interlocking LA and it became the new logo for the Los Angeles Dodgers.
The ascending baseball logo, which adorns the observation deck at the Top of the Park at Dodger Stadium, has been traced to Dodgers letterhead from the 1930s.
