In this July 29, 2012 photo, an artist who calls himself the Urban Maeztro and prefers to remain anonymous for security reasons, works on a black-and-white reproduction of Leonardo da Vinci's "Mona Lisa" holding a pink gun at his studio before hanging it in a public space in Tegucigalpa, Honduras. The 26-year-old graphic artist left his day job at an advertising agency to work on pieces like this one, to encourage Hondurans think about how violent their country has become.
