I am not one to verify anything but it looks like the type of ‘copy’ you get when you need birth certification for passports, etc.
Each state probably has their own style.

I think you are right. It pupports to be an official “copy” from modern tech I guess. I’d still like to see a photocpy of the original. That one really has no compelling reason for Obama not to release it as far as I can tell...and yet he will not.
