Went to the new Pompeii exhibit this past weekend at the San Diego Museum of Natural History. So did a lot of other people. It was crowded. But it was a good show. What made it most fun were the occasional bursts of graffiti on the exhibit walls. They were examples taken directly from the walls of ancient Pompeii. They were mostly about keeping your hair clean, putting charcoal around your eyes, etc. The original guerrilla ads (proving that insecurity and a desire to be beautiful are timeless). Here’s a little history on just how much graffiti was used in ancient times. People think advertising is new and hip. It’s as old as the hills.
