From eBay. This was the cover of a magazine, Plateia, issue dedicated to the memory of Queen Amelia. The magazine name and issue information were removed with Photoshop and the sepia tone was removed.
This is not datable with the sleeves under her wrap and her lower bodice and skirt out of view. She was a master of glamor.
