This earring is adapted from an art glass entry window design in the Susan Lawrence Dana House, Springfield, Illinois (1902). Frank Lloyd Wright used geometric abstractions of flowers, plants, and insects of the prairie in the more than two hundred windows, doors, panels, and skylights in the Dana House. The glass butterflies that inspired this earring welcome visitors in the transom window above the entrance door of the house. Finish: Solid brass, electro-plated with non-tarnishing silver finish, giclee print, ear wires are hypo-allergenic Dimensions: Hangs approx. 1.47" (Gift Boxed with Provenance Card)
