Hello! The signature is definitely authentic. I just received a success from her for my charity. It's the exact same photo as the one you received, but the signatures are in different places and have slight variations. I got a letter from Glenn Close's sec. as well saying that it is a pre-signed photo. The letter also said that Miss Close pre-signs photos for her fans and charity requests. I am paraphrasing, but that's what it said :P
Anyway, I hope that helps with your authenticity question! -Colin

Thank you so much for posting!!! Here's mine I just got a couple days ago. http://img837.imageshack.us/img837/4293/glennclose2012ttm.jpg IT APPEARS TO BE A PRE-SIGNED PHOTOGRAPH...AUTHENTIC!!!! (in my opinion). iYAY! :D Look at the way she signed her last name "Close." Yours is more legible as mine is a little more rushed and the "B" in "Best" is signed slightly different, too. I do not think this is a pre-print. Congrats!!!! :)

Not sure if its a PP or autopen, but its definitely not a sec. It's almost exactly like the one I got in person a few months ago.

congrats on the great success. quick too.

I think this may be a PP. The signature looks as if it isn't part of the photo but PPs are getting more authentic looking. I know she usually dates the photo and this isn't dated.

hi!
this is my authentic success from Glenn Close:

August 7, 2012, I sent a LOR and SASE to Glenn Close at Trillium Productions, PO Box 1560, New Canaan, CT 06840. I received a "Thanks" written on my letter and a photo of Glenn Close on August 16, 2012. Thoughts on authenticity?
