Hi Suzanne,

Thank you for contacting Mearto with your appraisal inquiry.
I have my doubts that this lamp is made by Tiffany Studios or Louis Comfort Tiffany, which are always labeled, usually on the underside of the foot and the rim (top or bottom) of the shade. Can you look for a mark and let me know if you see one? They can be quite small and not always easy to see...

Thanks to confirm when you can,
Delia
