native spoon

I was going through my grandmother's silver and I found this item which definitely does not go with all of the rest! I don't know anything about it but I do know that she passed through the southwest on her way from Ohio to California in the early part of the last century. Does anybody recognize this type of spoon? It's clearly a native design, perhaps that's corn woman on the handle, but I do not know when or where it is from. Would love to know more about it!
