A profile sketch of a woman with curly hair, dark makeup, and smoking a cigarette scrawled on concrete in the undercroft of the Lincoln Memorial could be that of silent-film star Theda Bara, according to a Washington Post report.

Forty-five feet below the Lincoln Memorial is art of a very different kind. On the pillars in the memorial's basement, where a visitor center is now under construction, is graffiti left behind by the workers who built the memorial to Abraham Lincoln more than a century ago.

Stephen Potter, a retired regional archaeologist for the service’s national capital region, cataloged some of the graffiti in the 1980s, noting “some that were extremely well executed.”
