If you notice it is like an overlay that has the then current office holders and their signatures. Certainly they do not sign each individually.
The older certified copies look like photographs of the original LFBC - still in a bound book. The bound book statement is due to the obvious ‘left bend’. Like scanning a book in a current flat bed scanner.
The post-1981 (and maybe earlier but the earliest I have seen is 1981) certified copies are obvious images out of a digital (likely optical mass storage) library. These images have a flat appearance.
The odd thing about the Obama Laughable Fake Birth Certificate is the fact that it combines the distinct left bend from the old ‘Nordyke era’ certified copies (i.e. mid-1960s) and the cross-hatch modern ‘security paper’ with a digitized image printed on it. No other LFBC certified copy that I have seen displays this odd combination. How surprising!
I think what we have here is another ‘abstract’ - created for illustrative purposes only...of course. They didn’t mean to fool their viewers, just show them what a birth certificate from Hawaii looked like. No harm intended...(sarcasm.)
