That appears to be a forgery. He did post an example from Hamilton but none of what he posted matches anything close to that. JFK had a quickness to his signature and that appears to be very drawn. It doesn't match any examples from that time period that I've seen.
As far as the campaign brochure, that is authentic and was a steal. To think I paid close to $1500 for the same brochure signed. Sucks. But that is the business I guess. That guy really should have brought it to PSA for authentication.....could have easily gotten over $1000 for it I'd imagine.
Very neat! Thanks for the link. I am very big into reenactments so I would have loved to gone there and seen that. I was lucky enough to be in Dallas Tx on the 50th Anniversary. It was my first time there and it was quite an experience. The highlight was getting to meet Clint Hill (JFK secret service). Even got my picture with him (which they said they don't normally do). As far as your JFK signed autograph, it is certainly authentic. Matches with the other standard JFK campaign autos he did.
