I love a bit of grafitti

I went "off piste" and followed a less used track through the wild garlic patch yesterday, which is how I came across the artwork. It takes talent to create much of what I came across. I'm guessing it's the work of more than one person, which got me wondering what they might do for a day job.
I know graffiti is not everyone's cup of tea, but there is a place for it, Banksy's done alright.
