In order for me to properly assess what you have I will need to see images of the front, back (do not remove from frame) and a clear, in-focus close-up of the signature.
If you had already attached images to your initial posting, they are not showing for me here on my end.
Please send the photos at your convenience. There is not an extra charge to provide more pictures here.
You can try emailing your images to *****@******.*** and write “For Nora/Antiques” in the subject line of the email.
Photos sent by email do not arrive to me directly nor instantly, they get forwarded to me by admin.
