Hello Mardam,
Sorry for the critics of your website

Your "old" picture really seems to show Auguste Ferdinanda instead of Elisabeth Franziska, maybe the source (your mentioned article) where you got it was simply wrong. There are often contradictions concerning the identification of pictures.
It´s interesting that you found a picture, which might be her!!!! Until now noone of us had ever found one!
From the title it could really fit, even then I wonder, if the Princess on the picture really can be already 48 years old (she was born in
1784 and the picture is from 1832), and I am not so sure, because in my view she looks a bit younger, but the picture is only little, so....

But if it is her, it would be great...! Thanks!

What do others think? Is there any bigger version of the picture available? It seems no...
