Obelisk Photo

The Obelisk Photo is a non-collectable story item found in the Sahara Laboratory. It, along with the Obelisk Drawings and Obelisk Sketch, serves as a sneak peek to the Resurrection Obelisk before the player actually finds it. Unlike the Obelisk in its current state, this photo shows the Obelisk not surrounded by wires, machinery, floors, and walls.

Originally the Obelisk Photo was found and could be picked up in Cave 6, right before the player descends down to the Armsy and babies that guard the keycard.

Theory
Theory 1) The Obelisk Photo was taken by a Sahara employee before they built the lab up around it. That is why it is found so close to the keycard, which also comes from a Sahara employee.

Theory 2) This photo was taken by an intrepid explorer who found the Obelisk, who then released the information to the Ethical Scientist Magazine. Someone seeking the Obelisk and its power (possibly a Yacht inhabitant) took the obelisk photo and the magazine, the only clues they could find, on their journey to find the Obelisk. They were unsuccessful, ending up in the cavern of bodies with only their magazine and photo left behind (along with a mangled corpse).

Theory 3) The photo was taken by the missionaries, hence the faded black and white quality and white missionary tents, and was later found and brought into Cave 6 by someone who had read the Ethical Scientist Magazine. This theory would also explain the room in Cave 5 with all of the missionaries crawling towards the obelisk cave drawing, as they would know about it, and perhaps its power.
