Secretarial---no doubt about it.
Around the time Arnold was running for governor the first time he started sending out some real autographs TTY. That was the only time in history I've ever heard about Arnold Schwarzenegger sending out real autographs through the mail.
I don't think that's an secretarial signature more like an Common fake you find on eBay etc, the secretarial ones look alot better than that even tho it's not signed by Arnold. Looks like it's been signed by an child.
He might have sgd ttm late 70s
