On Saturday, an old man set up a stall in Central Park near Fifth Avenue selling “spray art” for $60 per canvas. He was able to sell a few canvasses to three tourists for a total of $420—which isn’t so bad for someone selling street art. Graffiti artist Banksy revealed that the stall was actually a one-time pop-up shop that belonged to him, and the New York Post reports that the art could be worth as much as $31,000. Talk about windfalls! If I had passed by that stall, I probably would have kept on walking, to be honest.
