Posters

SPOILER

By numbering each of the posters, and determining what appeared, we can derive the following list:

1. 3 Roses

2. 1 Moon

3. 3 Shoes

4. 5 Clocks

5. 2 Bells

6. 5 Handcuffs (4 in the upper left pic, 1 in the upper right)

7. 1 Owl

8. 4 Bugles

9. 2 Doves

10. 3 Cards (2 in the ring of cards, 1 at the bottom left of the poster)

By finding the corresponding letter of each missing item (ex. 3 Roses, the 3rd letter is "s"), we get the phrase: SMOKE COLOR. The color of smoke used in the clues was white.

The answer is: WHITE
