LUNAR ROVER (APOLLO 16)

(P) If you look, there is a marker that goes behind the antenna of the Lunar Rovers equipment.

(Q) These cross hairs are placed between the lens of the camera and the film, so they should apear over the antenna. A bright, reflected light may have obliterated the fine line of the markere, or it may have happend when the image was retouched

(R) Examining the rock closer you will notice what looks like a 'C'. It could be a prop reference for a film set, or a mighty big coincidence.
