What did the first grafiti ever written read?

Question

Seriously, what do you think was the very first image or word?

Answer 1

Grafitti have been found in Pompeii, destroyed by a volcano in 79 AD.  Some of it mean, some of it humourous, some of it scatological.

Probably not the oldest.

Answer 2

There is some ancient greek words written on some pillasters in Egypt (or maybe it's the other way around) and it says ...was here....it's true... sorry though I don't know which 'way' it is...

Answer 3

I don't know. I'm not a paleontologist.

Answer 4

Keep off the grass.

Sorry, it was probably a hunting scene, showing others where the best hunting could be had.

Answer 5

graffiti=hyroglyphics

Answer 6

A picture of a dinosaur.

Answer 7

In the August, 2006 issue of Scientific American an article appears named Paleolithic Juvenilia.  The article speculated that drawings depicting s*x and hunting were done by juveniles. Caption reads "Disemboweled Bison gores a seemingly aroused man".
