I recall walking through a street of San Francisco (though I can't remember which one - maybe the Haight somewhere) when I saw a big spray-painted piece of art on a wall above the top of a building. I instantly recognized it as being in the style of Banksy. I doubted it at the time because I'm a London expat and it seemed too much of a coincidence to have your "local" artist suddenly turn up in your new neighborhood.

It was only later I looked it up online and found it was actually his work. I'm actually a little surprised that stall at Central Park didn't at least get a few people questioning who the artist was. Perhaps they did, but for brevity the video doesn't show those interactions, because they didn't end up buying anything.
