Two new books I am reading at the moment – both on Rock Art.
The Rock Art of Arabia Saudi Arabia, Oman, Qatar, the Emirates and Yemen
By Muhammed Abdul Nayeem.
This one came from India at R2000.00 (Good price thanks Page, he got a friend to bring it back for me)
Introduction to Rock Art Research, Second Edition.
By David S. Whitley. – thank you for the link Freyja.
I knew that if I kept looking, eventually I would find some.
