Legal art Vs Illegal ads
I was very surprised to discover recently that there are literally hundreds of illegal billboards in New York.
The ads on these poster sites are legitimate. It's the sites themselves that are illegal.
Street artist Jordan Seiler decided to do something about it.
Seiler organised a street advertising takeover which saw over a hundred of the illegal billboards whitewashed.
The resulting blank canvases were then given over to a group of artists to express their creativity on. Sounds like a fun idea to me.
