On the face of it, a disappointing bit of graffiti. Nothing that interesting.
They appear to be simple tags. In the Wildstyle form of graffiti common in the US. I understand that tags can contain subtle and cryptic messages. Unfortunately, too subtle and cryptic for me. I do hope the recipient of these messages “gets it”.
My favourite bit of graffiti was on the side of some derelict warehouses. It was written roughly in paint with each letter being about 6 feet high:
There once was a land full of laughing trees…
As simple as that. I use to see it travelling by train to work in the 1980’s. Many people used to look up from their newspapers or books and wistfully smile at it. I think the artist now is a serious name in the international art scene.
This recent painting and decorating in the subway seem to have been completed by someone with a serious grudge against style.
