Sorry about totally mistyping your name ... I was in bullaun shock!
That stone is the first 100% definite link between rock art and bullauns and basically confirms my proposal that bullauns are far older than the early Christian period that the scholars prescribe to them. Many have poo-pooed my ideas and now I can stuff it to them :-)
I will be coming to see this one for myself as soon as I can do so. It's a beaut!
