I disagree, the border is different from the known real version of this certificate yet the revision number is the same. I believe that there is some reason for this.. you see the lines in the border were it was pasted together.. on a real official document this would be cause to send the thing back to the engraver.
Folks have found some reason to believe that it was printed and folded and perhaps rescanned before being modified but I very much doubt that the original was truly a scan of a real Hawaiian blank certificate.
