It is the illustration of a face of an unknown male person that is located on the northern slope of Mount Chiliad near the cable car station. The face itself is drawn on a rock edge and appears to have been spray painted.
Upon closer inspection, the face bears a stunning resemblance to the face of Jesse Pinkman, one of the protagonists of the American television drama Breaking Bad. However, some players theorize that the face is simply that of a game developer. The strange easter egg has no purpose in the game's storyline. In the Enhanced version of GTA V, the face is replaced by a cock and it may suggest, that Rockstar thinks, that the man is a dick.
Although the easter egg is located on Mount Chiliad, it doesn't connect in any way to the Mount Chiliad Mystery.
