Photography of graffiti in Nottingham

Here are a few images of graffiti that i have taken in Nottingham. I think they are very interesting as they are advertising to remind people to recycle, but they are doing it in a way that people who may be littering may pay attention to as it is a clear message on the wall in the form of graffiti with bright, colourful images on the wall in places that littering may occour.

I think this form of graffiti can be justified as it doesnt offend people with offensive language, doesnt insult people and it atractive to look at. Although this is a large scale image people may say that it is visual polution, littering on the hand is a much larger problem as it destroying the planet and is potentialy harmful if a needle or broken bottle were to injure someone whereas this graffiti is not harming anyone.
