Thanks Bigg Red. Graffiti has been a widespread method of self-expression since long before gang-related tagging. Ancient graffiti on somewhat more ancient carvings and whatnot appears in Pompeii and other towns buried that day in 79 AD, in Egypt (including over the entrance to the Great Pyramid), the Hagia Sophia in Istanbul nee' Constantinople, and all the way back to the stone-age cave paintings.
