Sheldon, I believe yours to be real. It's a very yearly example of her signature. The concern I have with the one I posted is that at best it is questionable.
Thank you
Hi Walt,
Your signed image does look consistent with the best examples of her signature. The second one does not look even close to what I know her signature to have been throughout her life.
Best,

Very late to this game. I was asked about a vintage C. 1950 Kelly and was looking around here and online - the second signature shown above is a stunning vintage example. I found another from the same period posted below for reference.
