Earlier quoted context omitted.
Neither murals nor graffiti is art. None of those would have been accepted in any gallery some 30~40 years ago when standards were higher and the world didn't suffer from the high number of grown-up men who are hooked up on comic books and animated cartoons it suffers through today. A lot of it is just vandalism. None of it seems to be made by or for adults. 99% looks like it's made by some comic book fan on LSD. Alw…
Just so you know, the exact same thing was said about pretty much every major art movement over the past century and beyond. When you say, "None of it seems to be made by or for adults", the same was basically said of Salvador Dalí and Andy Warhol and Paul Gauguin and Henri Matisse. The more things change, the more they stay the same. :)
And I would actually claim that most Warhol is trash, good swaths of Dali worthless, and both Matisse and Gaugin mixed bags.
