Did they find anything close to the amazing grave goods discovered in King Tut’s tomb?
Nope, it was trashed. The only other ancient Egyptian tomb that was still loaded up was not of a pharaoh, and discovered in 1905. The second big Tut tour (uh, 10 or so years ago) included a ballustrade from the vanished city of Ahketaten and some sumptious treasures from that tomb, along with plenty of Tut stuff (just not the gold mask).
