Jackie Robinson swings the bat for Brooklyn

Jackie Robinson swinging the bat for the Dodgers in 1954 -- seven years after he was called up to the majors. Note his now-iconic uniform number 42, which has been retired league-wide by Major League Baseball. Note also the B for Brooklyn on his cap; the Dodgers didn't move to Los Angeles until 1957.
