Congratulations!

When he's young (like in your photo where he's using a hat) he's
HOT!
About your question, I did think PPs
were a copy of their signature.
I don't think it's a sec. Looks like a man's writing to me. Plus I saw a picture of an old signature of his in the 1970s, and it looks similar. I doubt he'd use seccretaries to sign for him when his career was beginning. And since the current one is similar to the older one, he would have kept the same "secretary" for 40 years? Unlikely.
This guy has a reputation for being a troll.
There's always gonna be a group of people that are like this
I know somebody's gonna come along and contend.
