We now define “Classic Monster” as (1) any early black-and-white monster that was (2) replicated in every medium and (3) well-know to every child and also human-sized. We can determine this list, the list of Properly Classic Monsters, by striking out any model in the Aurora Sixteen that does not meet these criteria. The result is ELEVEN —

1. Frankenstein (1961)
2. Dracula (1962)
3. Wolfman (1962)
4. Mummy (1963)
5. Phantom of the Opera (1963)
6. The Creature from the Black Lagoon (1963)
7. The Hunchback of Notre Dame (1964)
8. Dr. Jekyll as Mr. Hyde (1964)
9. King Kong (1964)
10. Godzilla (1964)
11. The Guillotine (1964)
12. The Bride of Frankenstein (1964)
13. The Witch (1964)
14. Customizing Kit #1 (1964)
15. Customizing Kit #2 (1964)
16. The Forgotten Prisoner of Castel-Maré (1966)

Result: Frankenstein, Dracula, The Wolf Man, The Mummy, Phantom of the Opera, Creature from the Black Lagoon, The Hunchback of Notre Dame, Dr. Jekyll as Mr. Hyde, The Bride of Frankenstein, The Witch, The Living Forgotten Prisoner of Castel-Maré Skeleton
