In the 80's I used to send out tons of autograph requests and then store them in my album. Since then I have compared many of them to authentic sig examples you can find on the net so I could sort out the real ones from the secretarial and auto pen ones, ect. The one photo I have not ever been able to resolve is this one. I have looked at some authentic examples on websites but still have no idea.

I was under the impression that Marlon never signed at all, the one I got I had just sent a letter requesting his autograph, I think the address was his home one I can't remember. 

I really did not expect a reply but I did get this inscribed signed photo back. (around 1988 or so)  Did he have a secretary who would sign, does it look like a know secretarial sig?

 Any help appreciated or thoughts appreciated on it being real or not.

Hate to break it to you, but it's almost certainly secretarial. He was known for sending secs out back then, and this matches them perfectly.
