Can you see it? It's on a supporting wall for the road on the other side of the stream that runs through Woodstock. I have met my match: found graffiti I do not like, even though this made a strenuous attempt to be art. It may have been shroom-fuelled, I don't know. Lots of mosaic blocks of images and colour.
Thanks to everyone who weighed in on the graffiti question, artists, garden designers and home owners alike. I found them thoughtful and thought-provoking.
