Help with poto school thing?

Based on the book?
1. The plain gold ring he gave to Christine, which she lost and he found again.
2. The fan his "lady" left in Box 5.
3. The manuscript of Don Juan Triumphant.
4. The "Little bag of life and death"
5. A reed. (To breathe underwater with)
6. A copy of Masque of the Red Death by Poe.
7. A false nose. (He wore such a prosthetic to the manager's retirement supper)
8. A bottle of laudanum. (To drug Mauclair)
9. You already mentioned the rope. It's called the punjab lasso and it's made of catgut.
10. A violin on which to play the Resurrection of Lazerus.

And a few more for extra credit.
11. The key to the gate on the Rue Scribe (eventually given to Christine.)
12. Stationary (for writing demanding letters), specifically with red ink.
13. A coffin. (He used one as a bed)
14. A bottle of Tokay wine. (Erik was a wine conniseur)
15. Flowers. It's mentioned that his home was filled with baskets of flowers.
16. Sugar cubes as a treat for Cesar, the white horse.
17. Barrels of gunpowder.
18. The wooden box with the strand of catgut inside used to imitate the voice of a lion of the buzzing of the tse fly in order to compound the illusions of his torture chamber.
19. Fake 20,000 franc notes. These are discussed in one of the chapters where the managers are trying to figure out just how the hell he Erik received his 'allowance'.
20. Very likely some memento of Christine such as a handkerchief, ribbon, or lock of hair. (Please note that keeping a lock of hair from a loved one was not unusual or creepy in Victorian times. Please google Victorian hair art/jewelry)
In the novel it is never indicated that he purchased a wedding dress for Christine. That is propagated by the Kay novel and the ALW musical.

bridal dress
organ
red death costume
candelabras
gondola
cape
hat
sheet music
