Jackie Robinson made his Major League debut on April 15th, 1947 and changed not only sports but American history. He won rookie of the year in 1947, MVP in 1949, 6 straight All Star appearances from 1949-1954, and a World Series in 1955. Robinson reached the World Series five times and lost to the crosstown Yankees each time. This led to the fans reciting their unofficial slogan "Wait 'til next year!"
Ever since cartoonist Willard Mullin lovingly depicted the Dodgers as "dem bums" and drew a likeness of hobo clown Emmett Kelly in the New York World-Telegram, the fans referred to them as such. From '51 - '57, some of Robinson's key years with the team, the Dodgers program was a drawing of a Brooklyn bum by Mullin.
Dem Bum pennants are 42% off from now until Sunday in honor of Jackie Robinson.
