Hello everyone. 

I'd like to ask for your opinion on this signature by Robert F. Kennedy. Taking a look, do you think it's an authentic or perhaps an autopen? I know RFK used autopen signatures on letters and photographs during the time he was in the Senate, but if there's any chance this one might be the real deal, I'd love to know. 

Here's a close-up picture of the signature on the photo. Looking forward to your estimations! Thank you all in advance!
