George Nash sent me his article about the rock art (adventure!) in the Serra Capivara, NE Brazil.
It can be viewed on Scribd and downloaded from there as a PDF-file.
Some of his photos, which I received last June, are now in the “Wordwide Rock Art Selection“.
George wrote further: “Those of you interested in looking further at rock-art articles from around the world or anything else, please go to the Current World Archaeology“.
Although not British Rock Art, it is at least Rock Art recorded by a familiar Briton. Thanks George!
