"Ping" to InspectorSmith and Seizethecarp
Good catch by David spotting the “broken foot” on the one typewriter.
The unevenness of the last line indicates it was typed at a minimum using multiple insertions of the form. These insertions could easily have been separated in time with one insertion in 1961 and the other after the statute that is referenced was passed.
I find it to be significant that so far no one has claimed to have “punked birthers” with this document. Someone has the original and they might have a lot of leverage over Obama or they might have had an “accident” among other possibilities.
Thank you for the update WhizCodger!
