Paperweights have long been a favorite among collectors and have been used as a means of advertising, souvenir appeal and decorative purposes. This is a great advertising glass dome paperweight from the late 1800's or early 1900's. It is advertising steam-driven equipment sold through a Cincinnati, Ohio firm. The paper disk under the clear glass dome depicts a large steam-driven machine in black on white background with gilt surrounding border. The wording states, "The Laidlaw-Dunn-Gordon Co., Cincinnati, O, U.S.A. - Waterworks Pumping Equipment" along with the picture of the machine. The round paperweight is 3" across and 1 1/2" high. The paper disk is very shape with a tiny "V" shape scratch; the glass dome is clear with one small, no harm, surface nick. A super item with cross-over appeal.
