From what I understand, it’s a temporary tattoo. I can see a young person doing it just for the notoriety, the gag factor. I admire the novelty of it. I could see skin care products. Imagine one saying “Soft, clean skin courtesy of DOVE”. If you take a creative approach the possibilities could be fun AND tasteful.

Those are all very clever new forms of advertisements. I am not so sure about the first form though, a homeless person trying to advertise certain company, well if they get paid for doing it then that’s fine at least they earn some money.

I have to say graphic waterfalls advertising rocks. Really an attention catcher.

I don’t think having a tattoo in front of your forehead is a good thing to do. It doesn’t look good at all to me.
