I'm sorry, but I don't understand the question you are asking.
Street art would last because of the way people enjoy that others would take the time and patience of creating these amazing drawing and only doing it with a couple of cans of spray paint.

I think the appropriate response is kouros statue. A kouros is a current term given to unattached old Greek models which first show up in the Archaic period in Greece and speak to bare male young people. In Ancient Greek kouros signifies "youth, kid, particularly of honorable rank".
