Ancient graffiti has been found in a quarry near Hadrian’s Wall in Carlyle, England.  The graffiti depicts an officer and an image of a penis.  Why does this matter?  It dates back to approximately 207 AD and supports the idea that graffiti writing is a generational activity that will not go away.  So, the next time someone asks me how we can make money removing graffiti I can show them a photo of an 1,812 year old piece of it.
