Yeti Print 1951

This photo was taken by a group on a recon mission for an attempt on Everest in 1951. The were at 19000 feet in the Menlung Basin when they found the tracks. They followed them for over a mile and couldn't find any other evidence. There are several interesting aspects to this print. The far left toe appears to have three smaller toes inside its circumference. There is an abrupt angle on the outside perimeter of the foot just down from the far right toe. Both of these are highly unusual for any print. Realizing this is from 1951 and prior to any Bigfoot or Yeti press adds credibility to the print.
