Vintage 1964 Humpty Dumpty Educator Picture Puzzle Plastic IDEAL 3172-4 HTF RARE

Vintage 1964 Humpty Dumpty Educator Picture Puzzle Plastic IDEAL 3172-4 HTF RARE. I think all the pieces here but can't find one to compare to online. Also, there is a space right above the left shoulder that seems like something should go there but Humpty Dumpty appears complete so I am unsure. This puzzle is vintage and used so check photos for condition. This is a rare, unique puzzle from 1964!
