When this stele statue head was discovered in 1983 , it had been used to build the wall of a house at Filetto ( Villafranca in Lunigiana , MS) . It belongs to group B because of the arc shape and side expansions and therefore dates to the Eneolithic Age ( between 3400/3300 and 2300/2000 b.C. ) . The sunken face is shaped like a rather tall U and the rounded neck is long and thick . At the sides of the face there are two couples of little cups . It is kept at Pontremoli Museum .
