Banksy set up a stall on the edge of Central Park selling 100% authentic original signed canvases, for $60 each.
Would you have bought one? [Ugh. Punching myself in the face that I wasn’t there to even consider it.]
That said, I think the results of this little prank/experiment/performance art piece may have been considerably different if the location was different. On the Upper East Side it’s all tourists and old money; hardly the sort of street-art-aware people that would have walked past if this was in the Village or Williamsburg…
