Steel. 6.25 x 3.5 inches. Imprint of The Homer Lee Bank Note Company, New York. Bright and lustrous light steel gray. Some light scratches are seen near the edges of the plate, but these are well away from the engraved design. A nice engraving of a steam locomotive pulling passenger cars on elevated track. Chicago's elevated railroad known today simply as the "L," began operation in June 1892. This earliest section of track is still in use today. An original paper wrapper is included, with a proof impression affixed.
