Colour lithograph poster, signed and dated in the bottom left and stamped with the London Underground logo in the bottom right. A duck pond with a bridge in the distance is pictured, with the bottom half of the poster showing under the water teeming with life, with fish of multiple sizes, frogs and an eel. Above the water are various birds including ducklings, a kingfisher, and a family of coots or moorhens. The vegetation is dense and luscious above and below the water.
