Picked it up at the newsstand for the Celtic Fringe article, but I found the one on the story of human DNA spreading across the golbe much more interesting.

National Geographic did a pretty good article on the Celts back in the late 70s when I had a subscription (before I ran out of room for the mags... could seem to bring myself to throw one away). It came with a fold-out map supplement that graced my wall in University res for a couple of years.
