Who else would set up a pop up shop outside the MET museum in NYC and sell original pieces and then report that they've sold only 6?

"The street prank gave Gothamist graffiti guru Jake Dobkin lots to mull over: Who's the joke about here, though? Is it that Banksy's work kind of sucks, from an empirical point, in that no one would buy it unless they knew who it was by? Or is the joke on everyone for not being smart enough to be there and recognize how valuable the stuff on sale was? As with all Banksy, there's kind of an edge to it that makes you feel a little annoyed—like he's having a joke at your expense.

But overrated, sure. In that what is fun to walk past painted on a wall somewhere easily loses something significant when it is detached from that context and elevated to the point much of his work is.
I live in a part of South London with lots of walls where street art is sanctioned, and I walk past a lot of it that I love where it is, but that I'd never consider putting on my wall at home. Banksy is a bit like that, in that I love that his work is out there on walls, but that doesn't mean it'd mean anything on my wall.
