If the CM house is coming, I would imagine this is our lineup of the monsters to be featured..
Phantom of The Opera (1925)
Dracula
Frankenstein/Bride of Frankenstein
Wolfman
Creature from The Black Lagoon
All of them, have a huge part in the history of Universal's classic monsters, and will be easy to show with ease. And for the case of Phantom, he was the first monster that Universal had for the Classic Monsters. Out of anything, he is the one to deserve the spotlight first, especially due to Universal's horror past.
