(This happened a few weeks ago, so I’m a bit behind in posting, but this is quite amazing.)
If you don’t already know Banksy, you should. He/She (do we really know?) is an artist doing art in public places (mostly), making you think. Banksy is currently doing a residency in NYC with lots of awesome stuff that you can see on the official residency website. The residency is for October 2013, but some pieces are likely to last beyond that, so if you’re in NYC, check it out!
Anyway, even though Banksy mainly does works in public spaces, he/she also has had pieces obtained by museums and individuals, and they are worth A LOT. That’s why it’s so amazing that Banksy set up a little stall outside Central Park to sell pieces at $60 a pop, each worth tens of thousands of dollars, to people that appeared to have no idea what they were getting into. If some art dealer or similar knowledgeable person would have found out, they probably would have tried to clean the stall out (if Banksy would have allowed it… unlikely).
You can read more about this event in a few different articles, too:
