Inauguration party for the "Rio Cruzeiro" mural painted in VIla Cruzeiro, a slum in Rio de Janeiro, Brazil by Dutch painters Jeroen Koolhaas and Dre Urhahn. The artists came up with the idea of painting the cement staircase - installed to prevent landslides by the city government - after painting another mural in the slum. They originally wanted to paint the entire slum, but soon realized that would be too much. It has helped bring positive news to community known for the dangerous shootouts of police and drug gangs.
