Aboriginal Artwork discovered in the Blue Mountains was reportedly created by non-Indigenous teenagers 50 years ago, according to a local newspaper.
The handprint artwork was discovered in April in the process of removing a boulder which threatened railway tracks west of Sydney.
Sydney Trains said it was verified as "culturally significant" by an independent archaeologist specialising in Aboriginal heritage, but according to the Blue Mountains Gazette, the rock art was created by non-Indigenous teenage brothers in the 1960s.
