Hello everyone. 

I'd like to ask for your opinions on the authenticity of this signature of Senator Robert F. Kennedy (1925-1968). It's from a signed photo sent from his Senate office, I believe sometime between 1965 and 1967.

Any comments on the authenticity of the signature are very welcome! 

Let me know what you believe: Is it authentic? Is it a fascimile signature? Is it a pre-printed one or an autopen? It's been bugging me all day, and I'm certainly not an expert. 

Many thanks to you all.
