 The album cover is a painting by Betty Swanwick titled The Dream . Swanwick had designed posters for London Transport between the 1930s and 1950s . The original painting did not feature a lawn mower ; the band had Swanwick add it later as an allusion to the song " I Know What I Like " as Swanwick told them that she had not enough time to paint a new picture for their cover .
