I would stay away from it.
It's very rare with MM signed photos.
I would recommend to only collect signed checks or authenticated signatures on paper of MM.
I dont know, A few things pop out at me. One that it is personalized Merilyn looks like she took her time with this. Maybe she was signing for a friend or a younger fan. Most people that sell fakes only just sign a name nothing more. I took the time to match her writing to old letters she wrote and I believe that this photo is real, and not a fake. Lets not forget that at that she was really famous.
