The front side of an embossed document would be raised and read normally, but the back side would depressed and read in reverse.
I'd have to go and look at it again though.
That’s correct. And the one on Obama’s COLB is exactly the opposite. The text reading forward is depressed. The text reading backward is raised. All of the examples I’ve seen of Hawaiian short-forms have the text reading forward as raised and the text reading backward as depressed.
