Looks like autopen on rough texture paper.
Ya it's an odd one
The signature appears to be slowly applied, but sometimes for NASA presentations they used a rough, bumpy mat that could cause that effect.
Vintage NASA presentation with bumpy mat or clever forger?
In my view, this item requires an in-hand review to see the full context before issuing even a cursory opinion. Is the mat is the proper age and type used by NASA, framing materials, age of the ink, etc. etc.?
