1) Why is the scan quality so strange?

2) Have you zoomed in to inspect the “typing” - its not typing at all, it’s printing. The words are all ghosted on a white background (zoom in 800%)

3) Why are the O’s in Oahu and Obama different fonts? If this was a real typewriter it would be the same.

That looks like unsharp masking was applied to the image. If you look at the parts of the image which are less sharp to begin with, especially the document number 61 10641, you'll see less of an artifact. Many digital cameras and scanners do this type of sharpening automatically unless you turn it off.

Unlike the Certification of Live Birth released in 2008, I don't see a lot of JPEG artifacts like two dimensional "ringing" at sharp boundaries. They didn't do as much data compression on this image.

“3) Why are the O’s in Oahu and Obama different fonts? If this was a real typewriter it would be the same.”

In Oahu the O is followed by (unshifted)lower case chrs.

In OBAMA they are all UC causing them to look different.

Why are the O’s in Oahu and Obama different fonts? If this was a real typewriter it would be the same.

What jumps out at me is that the O's in both Oahu's are not in line with the rest of the word, they are a little high. However, in OBAMA, which is all in caps, the O is perfectly in line with the rest of the word.

Two different "typewriters?"
