I can see the crimp damage caused by the impressed seal. I can also see a very faint bleed through of a rubber stamp right above the bottom frame near the center.
What I’m having difficulty discerning is basket weave in some of the letters in his father’s name.
The overall resolution is good enough that I should see it, but I don’t. I suspect it’s an artifact of the imaging system/software, low contrast features near high contrast edges are often suppressed to improve perceived sharpness.

Is it possible the answer to your question is contained in this previous post? Images at link. See:

“The typeface on the Decosta image is much darker and thicker, and has less kerning (spacing between the letters), than the Obama image. Moreover, the color of the green paper comes through almost all of the letters regardless of magnification or image compression.
By comparison, you will not see the grey and white pixels found between the letters on the Obama image.
When you enlarge the letters in the Decosta image, they all tend to remain solid, especially letters like “I, L, B, E, H,” that continue to look the same no matter how large you make them. Conversely, when you enlarge the letters in the Obama image, they start to fall apart — that is, they start losing pixels. This is exactly what happens to bitmapped text created by a graphics program.”
