The enigmatic Cuevas de las Manos (Caves of the Hands) in Argentina is the largest and most dramatic display of hand prints in the world. This ancient rock art exhibit is believed to have been painted more than 9000 years ago.
The majority of the paintings are hand prints, but some also include depictions of guanacos, rheas, hunting scenes and images thought to be aliens and evil spirits.
UNESCO has declared the cave and its paintings a Heritage Site for its large scale and the painting method.
