Cueva de las Manos (Cave of Hands): 

“…A cave or series of caves located in the province of Santa Cruz, Argentina…famous for the paintings of hands by indigenous inhabitants some 9,000 years ago. The composition of the inks is mineral and therefore cannot be carbon dated, so the age of the paintings was calculated from the bone-made pipes used to spray the paint onto the wall blocked by the hand.” 

Not sure how old that quote is but I believe paintings can be dated using accelerator mass spectrometry
