Whilst reading the news this morning I ran across this:
http://news.yahoo.com/s/ap/20070716/ap_on_re_eu/ancient_maskMore ancient artifacts are being found near the area featured in the National Geographic article from the Dec 2006 issue. This area has been dubbed the "Bulgarian Valley of the Kings" which of course referrs to the Egyptian Valley of the Kings--this is no small comparison!
It's always good to see Bulgaria featured in the news!
