The image is a vintage, black and white illustration of a tall, lattice-work tower. It's reminiscent of the Eiffel Tower, but with a more elaborate and ornate design. The tower is constructed from a network of interconnected beams and supports, creating a complex, geometric pattern. The base of the tower is wide and gradually narrows as it ascends. Above the tower, the text reads "DESIGN No. 41". Below the tower, the text reads "J. TERTIUS WOOD, F.G.S., ROCHDALE.". The background is a pale, off-white color, giving the image a historical, aged appearance. The number "90" is visible in the upper left corner.
