Its not Urban Spam...Its art! Well depends on your definition. Piers has brought up an interesting point about the over-proliferation of street art. I tend to think this is more the case of metropolitan places like New York City, where clutter is everywhere and often people pollute space hopelessly wanting someone to notice. While less dense populations can have urban spam as well, the outdoor adverts are usually cookie cutter signs (McD's, Restaurants, gas stations etc.) If someone of good branding skills were to come along, they can often rise & create meaningful connections (Banksy, Obey among others). So the lifefilter is here to help you make a difference by adding a little art to your world. Who knows you may have the next suggestive underground brand all powered by your sticker.
