Ancient Native shops America Effigy Stone

Product Name: Ancient Native shops America Effigy Stone
This is a personal find that i thought would always be in my personal collection. Its such a cool piece. After discussing with many other collectors, we have two shops conclussions on what its purpose served. One, an effigy stone face( which i can several different distorted faces). Or 2, some sort of shaman made stone. Very cool piece i found near the creek on property I have permission to hunt on. One of the drilled holes goes all the way through the stone. I hope its new home will display it as I have. It was the topic of all new comers at my house.
