The image is a vintage illustration of a tall, conical tower. The tower is depicted in a detailed line drawing style, with a spiraling pattern wrapping around its exterior. The base of the tower is wider and gradually narrows towards the top, culminating in a pointed apex. Below the tower, there is text that reads "J. HORTON, COPLEY, NEAR HALIFAX, YORKS.". Above the tower, the text reads "DESIGN No. 17." and the number "42" is at the top of the image. The background is a pale, off-white color, giving the illustration a classic, historical feel.
