Really cool and unusual! 3" long and 2" wide at widest point. Heavy lead head with closed eyes and sewn mouth. About 1/2" thick. This is a factory test molding of the original Shrunken Head Fright Factory Mold.
Just in case your memory doesn't serve you, we have provided reference pictures not only of the original mold (not included) but also the insert (not included) that went with this mold which should not be confused with this rarity. For further reference, please note the lack of connecting points on the back which would either be there or show signs of grinding if this were the clearly less detailed insert. Excellent condition. Probably near one of a kind.
