Looking for age of this photo please family unknown

I was looking through some of the earlier posts and came upon yours.  Is there any chance that the scroll could be a narrow book or journal?

I tried to replicate the photo, rolling up a piece of paper and holding it, and the first thing I did when I placed the "scroll" in my lap was to also hold it with my other hand.  I don't see her left thumb, so she was either told to hide her thumb or she didn't have the same reflex that I had when my hands met.

Apologies for contributing a strange idea (a book), but if it was a scroll she exercised a lot of willpower not to hold it with both hands.
