Have you ever heard a howler monkey? Terrifying. Fortunately, this puzzle of Farid Rueda's howler monkey mural in Armenia, Colombia is far from terrifying. In fact, it’s exhilarating. As part of our inaugural Street Art series, Rueda's mural is full of bold color patterning and is simply jaw-dropping (get it?). We hope you enjoy putting this together as much as we do.
