MLB’s Commissioner's Trophy
Seen here with Red Sox pitcher Pedro Martinez and his teammates after the Sox won the World Series in 2004, the Commissioner's Trophy is awarded to the winner of the World Series every year.
It's the only trophy in the four major North American sports leagues that is not named after a particular person, and it features a flag for each of the teams in Major League Baseball.
Unlike in hockey, a new trophy is given to the Series winner every year. The trophy is approximately 24 inches tall and weighs 30 pounds.
