The seller claims its not a secretarial but rather his uncle got it autographed from trump while in a restaurant many years ago. He also claims it will pass jsa or psa authentication.
I think that ones a secretarial. I'm not sure how long he used a secretary but there are two distinct ttm signatures I've seen. One was where the D is more noticeably a "D" as opposed to this one shown which seems to be a copy of the original (possibly real) ttms but the D is like a backwards D or more like an "S".
I got his autograph ttm three times and have deemed my receiving with the "S" D to be secretarial. The other two with more pronounced Ds I'll never be sure. LOL. Nothing ttm I've seen really ever looks like his in-persons scribbles (even pre-presidential run) though some ttms with pronounced "D" seem to match his official document signatures.
