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

7. 1 Owl

8. 4 Bugles

9. 2 Doves

10.???

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

VirtuonDG: The tenth poster has the 3 of diamonds appear, so it's the "3 card" which gets the R needed. </spoiler>
