The black field you see does not cover a certificate number rather it hides the fact of its non existence.
Very interesting. Thanks for your post! I hadn't thought of nonexistence as a reason for redacting the certificate number.
The poster of that analysis made a compelling argument which connects a lot of dots.
Although the 4 days between birth and filing are enough to travel anywhere in the US even back in the 60’s, I doubt a new mom would make the trek from Africa to Hawaii so soon after birth.
If the poster is correct, I suspect more practical reasons for the incomplete filing.
