If you are going to the Heritage center you are in for a treat. The Yupik display gives a pretty good overview of the older days and the pictures inside are phenominal. Go to the gift shop and ask fro Mary Oxley's work, she just shipped some up there, they might have some in stock and maybe on display. Any souvineers purchased there are made by Alaska Natives, all the other gift stores in town sell chinese made replicas or massed produced by whitepeople on assembly lines although they will swear to you they are not.
thanx,
