Art is where you find it

Or in this case where you can hardly see it. This billboard (A) appeared in Wellington, um… sometime in the last month or so. Thanks to climbing on a pillar support (B) we can tell you that this Paul Hartigan work is called something like Two Bob a.k.a Puff Daddy… the rest is invisible to all but the seagulls. Who put it there? What is it all about? Table tennis ball anyone?
