back in the day, when someone didn’t physically sign something but their secretary signed it, the sec would add their own initials indicating it wasn’t a direct signature. I often would sign for my boss and put my own initials there.
Maybe the signature was the secretary’s as well as her initials.
Where did Roy Moore go to high school? Did he sign another yearbook to another person when he was actually in high school?
No...That doesn’t make sense...It was probably a signature stamp which is/was quite common.
