‘Atlantic Grey Seal’ color scrimshaw on ancient walrus tusk ivory net sinker by David Smith. The grey seal is now listed as a protected species, although that could change in the future. Most remember the grey seal pups that used to be harvested off the Newfoundland coast in the 1970s. Scrimshander Smith has depicted an adult in this fine work. His work is always top of the line and this is no exception. Interesting piece of ivory in that it was used as a net sinker by natives in the Northern Bering Sea area hundreds and hundreds of years ago and it was also used as a fire starter as can be seen on the reverse side. Early version of the Swiss Army knife multi purpose tool.
