One of the interesting things that I see everywhere I go in Dublin is what I've taken to calling "Pole Art". On virtually every pole, be it for a street sign or a lamp post, someone has put a sticker. These are either some kind of guerrilla marketing for something, or just plain street art. Some are pretty basic, others are quite good art wise, and some are quite witty. I suppose they are technically are graffiti, but I do love the variety of them.
Over the last few years I've collected quite a library of them. You'll often see the same ones for a while on lots of different poles, and then there will be a new wave. I try to take a photo of them whenever I can. My goal is to collect a huge library of them, and maybe someday create a book, or a poster or something, as there really are a lot of them.
Anyway, here is a very small collection of some of the stickers that I've seen from my "Pole Art" collection. Enjoy.
