OFFICIAL WASHINGTON D.C. FLAG HAT
The Official flag of Washington, D.C. Hat, consists of three red stars above two red bars on a white background. It is an armorial banner based on the design of the coat of arms of George Washington, first used to identify the family in the 12th century, when one of George Washington's ancestors took possession of Washington Old Hall, County Durham, northeast England.
In a 2004 poll on the North American Vexillological Association website, Washington, D.C.'s flag was voted the best design among U.S. city flags, just out-polling the flag of Chicago.
