Mask painted wood that represents Garuda

Mask painted wood that represents Garuda, the bird man, often mounted by Vishnu and usually found on bended knees in front of the temples dedicated to Vishnu or as a guardian of the mountain caves sacred to this god.
He is represented with human features, except for the big, opened wings. He sometimes has (as in this case) a bird’s head, in particular a raptor’s one. It’s considered the ancestor of the sacred lineage’s birds, also seen as the messenger between men and Deity.
On the back, part of the Customs wax seal attesting the authentic Tibetan origin.
