Located in Argentina, the Cave of the Hands (Cueva de las Manos), is the main place to find Hand It cave art. The cave features stencils of hands (speculated to be made by spraying paint through bone-pipes) and is estimated to be between 9 and 13,000 years old.
Undoubtedly, the cave is most famous for the hand stencils, yet it is also home to drawings of patterns, animal and human figures, and other shapes.
