As a new member, I am loving reading through threads, seeing examples and hearing stories. 

Found this (post) from Eric K. Longo regarding "Invasion of the Body Snatchers".   Although I am sure mine is a repro photo and not vintage still (and unfortunately, I have not met either of the actors - Scott Paul), the signatures seem to match up nicely. 

Please share any POV on authenticity.  Thank you.
