Do you know about the priceless Picasso that was lost in an airplane crash? Or the sad fate of some fundamental fossils found outside of Beijing? This episode of The List Show is all about Priceless Things We’ve Lost Forever, from natural wonders lost to the ravages of time to impressionist paintings lost to the ravages of…an overzealous dorm master. Erin discusses sad moments in history when unique and valuable objects were destroyed by human beings, as well some really cool things that were just lost through happenstance. She even throws in one item that a museum nearly lost track of entirely, before it was triumphantly returned to its place in the historical record.
