LittleBigPlanet/Unused Stickers

Unused Stickers
These are stickers that are not seen anywhere in story mode, nor can you obtain them.

Uncollectable Stickers
While technically not unused and can actually be seen in the game, these stickers are uncollectable as they were never given as a prize in any levels.

In-Game Photos
Strange photos taken in-game by developers. Some can actually be seen in-game, but most aren't.
