Walrus Ivory Eskimo Carved Seal Button with Circle and Dot Motif

This is a small ivory carving of a seal with 5 rows of "circle & dot" design across the top. The seal may have had hind flippers at one time but they either broke off or possibly were not successful and carved off. When examining the back of the carving, it does not look like a break.
