Maine's 1901 state flag is not only historic, but full of maritime meaning. The North Star has long been a navigation tool for sailors and the pine tree made our state's unique flag recognizable from great distances. Even the flag's background color had meaning, it was meant to resemble the buff color of George Washington's 1779 Continental Army uniforms.
