Ah, graffiti arts, they live and die with their canvas...
And yep, I also wonder how they do some of their stuff when I see them, specially if the graffiti is at a place that is hard to reach, like on the side of a fenced off highway bridge, and so on.... I supper graffiti artists are rulebreakers, so I wouldn't be surprised of their 'creativity' of being able to leave their marks at challenging canvases.... XD
Nice photos, hiddi :D
Haha yes! And the fact that they can do this fast enough with an awesome outcome is impressive.
