In order for me to properly assess what you have I will need to know the size and see images of the front, back (do not remove from frame) and clear, in-focus close-ups of the signature/small print.
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.
