Phantom philately- carried by Yeti!!

Nepal philately has had been famous for many expedition covers, some genuine and some philatelic. These helped to market the expeditions effectively. In some later stages, the marketing gimmicks through philatelic means became more and more bizarre. For example this cover, signed by the expedition members of the Argentinean Himalayan expedition dated 15-10-1979 is purported to be carried by YETI (!!!!) . Or as is known in many circles as the Abominable Snowman.

Obviously this idea of an Yeti Postman is the most fantastic hoax concocted out of a fertile imagination!!
