Diablo rojo, Panama

A diablo rojo, or red devil, in the highland town of Volcán in western Panama in 2012, with an airbrushed portrait of Jesus filling its rear emergency door. Like Guatemala's camionetas, these are retired American school buses, but Panama's painters turned them into rolling murals of graffiti lettering, religious images and portraits of popular figures. Panama City began replacing them with its Metrobus system in the early 2010s, which makes a well-kept survivor a real find.
