It measured 70 inches tall, with a shade diameter of 24 inches. A 20th-century Duffner & Kimberly leaded glass lamp shade, estimated at $300 to $500, realized $22,800. This hanging, domed shade had a floral motif and was primarily rendered in green and blue glass and was sold with a two-socket hanging lamp fixture on long brass chain. An archive of ephemera related to the late 19th/early 20th-century chocolate industry was estimated at $300 to $500 and made $5,280.
