Here’s the State Registrar’s stamp from Barack Obama’s long form birth certificate.
“TXE” is what it looks like; however, it may be instructive to look under the covers. It is widely reported that the long form PDF file we’re viewing is made up of layers, including a background layer and separate layers for various objects on the form identified during PDF optimization. The Onaka signature stamp is essentially a separate object (or layer). It’s instructive to look at that layer in more detail.
I used the Export feature of Adobe Acrobat to get the following actual sized image which is only 76 pixels per inch!
When one zooms in on this, we get a better idea of what information underlies the the pure black part of image:
The right vertical stroke of the “H” is complete in the bitmap. Added to this image should be other non-purely-black smudges from the other layers.
So yes, it looks like an “X” but it isn’t. Why is it like this? Low resolution of the stamp is certainly important, and maybe the stamp is damaged due to wear, or a bit of lint accumulated in the middle. The real reason probably won’t come to light without a higher resolution scan or examples of other stamps from about now. I asked Barry for a better copy.
