Christie's is going to auction off this ancient mask from the Judean desert. It looks very similar to one from the Hirbat Duma neolithic site that the one the Israeli State Museum says is the oldest mask ever found:
Christie's dates its mask to the 7th millennium BCE, which the same date the Israeli State Museum gives for theirs. So you could buy one of the oldest masks ever found, if you have the cash. The pre-bid estimate is $400,000 to $600,000.
