The variance of the inner workings of the human head! A thing we at Nevertold never could tire of. This skull is, unmarked but was a Clay Adams preparation according to the Doctor from which it was purchased. Ever wonder how your teeth are hooked up? Or what the inner working of your sinus cavity or ear are all about? This smiler has conveniently hinged cutaways to answer all your burning questions without the need for self surgery! It is one of the nicest examples of this type of preparation that we have seen and comes with a carrying case for an evening out on the town!
