American Daisy Leaded Chandelier

Ed. This shade was in a well known New York collection where, in 1976 it was thought to be by The Kimberly Company, sucessor to Duffner & Kimberly.
If that is accurate then the shade would be dated to after 1910 when Duffner & Kimberly failed and Oliver Kimberly restarted the business.
More details on this are covered in Mosaic Shades, pages 167-169. Whether this attribution is accurate remains to be seen.
