Fascinating, I do love street art and tastefully done graffiti. Some of it is obnoxious. I think it does add to the character of a city e.g. New York, Berlin, Montreal, Paris all have some amazing work etc.

I submit Irish Graffiti I see here: https://old.reddit.com/r/Graifiti/

Though I think displaying these things as a map is more useful: https://streetartcities.com/cities/sanfrancisco

There is a an Irish artist called Dan Leo and I have bought lots of his prints. https://www.danleodesign.com/ so they are dotted around my office and home.

I think they're great! He does animals and I love the style, clean lines and bright colours, they remind me of US football team logos.
