Missing Poster#23

Missing Poster is an unlockable trinket. Note that this footage only applies to the Rebirth version of this trinket and does not show the changes made to it in Afterbirth.

• The first scenes in Ending 15 and Ending 17 show The Missing Poster pinned to a utility pole, with a silhouette of Isaac's mother who seems to be searching for Isaac in the background.
• There are many puzzle pieces in total. Assembling all of the jigsaw puzzles and figuring out what they meant was initially designed to be a collaborative effort of the community. As such, Edmund and Tyrone had openly expressed disappointment towards the datamining.[1]
• The unlock pop-up of Missing Poster calls it "Lost Poster". It is unknown if this is a mistake or a hint.
• A chest always containing the Missing Poster will appear as a room clear reward from the Dogma room, although it is impossible to access it without the use of console commands.

Bug! Internal Item Descriptions do not show the fact that holding the trinket revives the character as The Lost (or Tainted Lost).
