The writing near the face

New photos have been released by MSSS on the D&M pyramid. They also show an area on SP122003 that appeared to be writing. At first glance this writing appears to be missing from the new image, but because of the low sun azimuth in the earlier photo the letters may be standing out in shadow. To test this I overlaid sections from both images, to form an animated GIF here:

 

 

and here is a smaller AVI file of the overlay. Each image has been oversampled to 288 DPI and adjusted with brightness, contrast and intensity. The results should be treated with some caution as this can introduce artefacts into the images.
