A huge collection of world art is available online at the Metropolitan Museum of Art. This “charger” (which won’t do anything for my cell phone) was owned by Winifred E. Higgins, who lived at 2401 E. Second St. in Duluth.
The charger was manufactured by the Kalo Shops, which Wikipedia calls “the leading maker of Arts and Crafts movement silver in Chicago.”
(I didn’t know either — a “charger” is a plate that sits under the other plates. Your server places your salad plate atop your charger, then your soup bowl atop your charger, then your dinner plate atop your charger, before the charger is removed for dessert.)
