15. One Stolen World War I Gas Mask Showed Up In A Pawn Shop
The curators of Wyoming State Museum searched high and low for almost a century for their stolen World War I gas mask. Formerly owned and donated by US Army Sgt. Robert O. Pennewell, the gas mask disappeared nearly immediately after its placement in the museum’s collection.
While searching online, officials found the mask for sale by a pawn shop owner in South Dakota. The owner listed the costume for sale on eBay for $300. While his heart sank to the bottom of his stomach when he found out the mask belonged to the museum, he happily gave it back to them.
