A Bit Of Graphic Trivia

I happen to pass this street art everyday, why is it there? ... I haven't worked that out yet, as it only covers part of the wall which seems a terrible waste of space when you take into consideration the eco-environment factor that is constantly shoved down ours throats, after all if it were a piece of paper you would be only using a portion of it and would have to throw the rest away.

Why do I like it? ... I don't really know if I do if you consider that I pass it nearly every day and on that way you have to pass Woolworths, and every time I hear the Woolworths jingle (which is several times a day) I inadvertently sing along to it ... but do I like them? ... I just don't know anymore. I'm just a part of the machine I guess. Everything I never wanted to be in life since I learnt about contraceptives and unfortunately didn't use to it's greatest advantage.
