Cartagena is full of surprises. While on a recent visit to the Colombian coastal city, I was fortunate enough to stumble upon a collection of prolific street drawings tucked away on a clandestine street in the city’s Getsemani neighborhood. These drawings, I later learned, were different depictions of Pedro Romero—a revolutionary war hero during the early 18th-century uprising against Spain. Romero’s true depiction is unknown, so in memorium, various artists gathered on this street to pay an aesthetic tribute to the late martyr.
