J'existe

I see these stickers all over Europe. It translates from French to "I exist." I am unsure if they are part of a campaign or an advertisement; and I have no idea who is doing this, but I think they're interesting and, some of them (not necessarily this one) make for good conceptual photographs based on their placement. This was stuck on a lightpost in Brussels, Belgium in the main square of the city. You can tell by the raindrops on the post that I was very uncomfortably drenched at the time.
