Authorities in Colombia’s capital Bogota have agreed to not remove graffiti as long as the street art is performed “in a responsible way,” following a meeting with graffiti artists who previously had claimed they were being persecuted.

When Rag & Bone, an American fashion label, opened its doors in 2010 in Manhattan’s Nolita neighborhood, it was met with an unwelcome surprise. The white walls of its building were vandalized by locals and tainted with scribbles and markings. Out of this initial eyesore, the owners decided to transform the wall into a creative space for artists to showcase their artwork.

A street artist is dedicated to repainting the graffiti daubed by street-gang members around his Chicago neighborhood, transforming the vandalized walls into naturalistic landscapes, comic-strip characters and historical figures of the United States and Mexico.

On Saturday, Yemeni artist and activist, Murad Sobay, launched the '12th Hour' campaign, a series of graffiti murals that will be displayed across the walls of the capital Sanaa to address 12 issues facing Yemenis today. Sobay, 25, said that while art was once thought to be religiously forbidden or 'haram', many Yemenis now join him in painting the walls of their capital. In the first hour, Sobay tackled gun ownership. According to 2012 figures, Yemen has the second highest rate of gun ownership in the world, with nearly 55 guns for every 100 Yemenis.

It’s a classic image of England, but “classic English” isn’t what I’ve come looking for today. Quite the opposite, in fact. I’m here in Bristol to explore a side of this historic port city that hasn’t always been smiled upon by the establishment, including the local police. I’m here to see graffiti. Walls and walls of graffiti.

Once again the debate about the arts and their relationship to the economy has been enjoined, this time in the UK. The terms are by now entirely familiar, and certainly loom in any discussion of the “value” of the arts in the U.S. as well. This is particularly true for the U.S. during recessions and periods of fiscal austerity.

Early in the fall semester, the University of Pittsburgh's Panthers for Israel group kicked off the year with free giveaways, music and a creative twist. Three renowned graffiti artists from New York attracted hundreds of Pitt students as they painted an homage to Pittsburgh and Israel on campus walls.
