Throughout the month of March, a unique graffiti campaign popped up on the walls of several streets in downtown Ho Chi Minh City, the hyperactive commercial capital of Vietnam. The works differed from the usual tags and designs that adorn urban areas around the world. The graffiti pieces, 17 in all, carry a simple message: "Save the rhinos" or "Cứu tê giác" in Vietnamese.
