Received the following from George Nash:
Dear friends and colleagues,
Enclosed is a paper that was published in Archaeology in Wales which I have managed to get turned into a PDF. It is basically a round-up of recent rock-art discoveries in Wales up until 2006. Several more significant discoveries have been made since then and will be sent on at a later date.
