Drymounting a Large Autographed Photo? A No-No?

[Mr. Zipper]

I would use archival mounting tape and mount it along the top center to a foam core backer. This way, it will hang down and not get wavy, but you can remove it from the backer if you ever want to.

One thing and speaking as a photo person, large modern photos are often shipped rolled these days, and I don't think that causes any issues when it's rolled flat. I've purchased and shipped photos rolled (just modern, never done it with an antique). They usually flatten out fine.

Personally, I would see if you could get it matted and framed as is and see if it works. It might.

Thanks for all the help guys. As a bit of an update, I went to my frame shop today (I live in NYC, so I used 567 Framing), and after speaking with them for about 30 minutes on choices, we went with cold press mounting on an acid-free Sintra (PVC like substrate) with archival mount. This should protect the photograph and keep it flat, take out any creases currently in it, and be almost 0% risk of harming the signature.

After the mounting, it will be placed in frame.

I'll keep people posted as to how the finished product comes out.
