Graffiti

I've been looking at this image on my computer desktop for a few days and started noticing more things the more I looked at it (like we all do). I was wondering how it all worked as a whole. And then I wondered when and where the photo was taken, and if these paintings are still on this wall today. Just as long as graffiti was considered a threat to clean public property, it's been a way to express through art. What does this wall/image express? Who might have the artists been? What did they each want to say?

In the far right, in the archway is a faceless and hairless child in a red unitard and yellow cape making loop-de-loops around the snow-topped and -bottomed skyscrapers of New York. In his hand is what looks like a beer or wine bottle. Is this superhero kid drunk or is he making a delivery, in which he took a few sips just to make sure he got the right one? Is this painting a protest against drunk flying? If it is, huccum super kid hasn't splatted on the side of a building in a super bloody mess?
