Thanks to the real estate bubble bursting and the ensuing recession, there are tons of vacant retail spaces all around Manhattan. What to do with all this prime space? One solution is to cover it with illegal advertising.

No Longer Empty has a much more elegant solution. The group is working with landlords to turn vacant storefronts into temporary art galleries that are free and open to the public.

Using empty space for the public good!
