While plaques at the Mall entrance memorialize President George Washington's farewell address and President Abraham Lincoln's Gettysburg Address, the primary themes of the statuary are to the past mayors, with the dates of their terms in office.
虽然在入口处牌匾是纪念总统乔治·华盛顿的告别演说和总统亚伯拉罕·林肯的葛底斯堡演说，但是雕像的主题是过去的历任市长，及在任日期。
