This photograph of a proposed Yeti footprint was taken by Eric Shipton on
November 8, 1951. It was Shipton’s fifth expedition to Mount Everest when he discovered the print. To show the size of the print, Shipton carefully lay down his pickaxe beside it in the snow. The print is 12 inches in length and 5 inches across.
In 2014, the original photograph sold at auction for close to $5,000.
