The Post Office building on Pennsylvania Avenue in Washington, D.C., decorated with flags and bunting for Flag Day in 1913. Large American flags hang through the open courtyard while smaller ones line the balconies, turning the building itself into a patriotic display. At the time, Flag Day was gaining wider recognition, especially in federal buildings tied to government and public service. Scenes like this show how national symbols were used in everyday civic spaces to reinforce a shared sense of identity.
