Skulls

It's more of head hunting than cannibalism. The Northern tribe warriors practiced head hunting even as late as the 40's or 50's. There was a ritualistic and spiritual element into it as well as pride. Head hunting is a result of warring tribes, vendetta, manhood rite of passage etc...They believed that keeping heads would guard them from vengeful spirits of course tasting blood or parts of human flesh would come with it but not so much as for food as in a Bristish expedition that got stock in the Arctic. So again it's not like " hey we ate the bodies cause we are hungry and we got heads left overs and we are keeping them as trophies and souvenirs!" Some museums would like it pictured that way couse it causes a sensation. It's more of a warrior to warrior sort of thing.
