The Boston Citgo sign is a large, double-faced sign featuring the logo of the oil company Citgo that overlooks Kenmore Square in Boston, Massachusetts. The sign was installed in 1940 and updated with Citgo's present logo in 1965. The sign has become a landmark of Boston through its appearance in the background of Boston Red Sox games at Fenway Park.
