Official Rules For Yeti Seekers In Nepal, From 1959

Apparently there was interest enough in finding/capturing a Yeti, that the government of Nepal set up a license and certain rules towards Yeti expeditions. According to this document from 1959, the license for a yeti seeking expedition cost INR 500. The expedition had the permission to photograph or capture a Yeti, but shooting or killing one was prohibited unless for self-defense.
