The black and white digipak for Duffy's album "Rock Ferry" uses images and minimalist design to tell a story. The front cover shows Duffy on a train, suggesting a longing for freedom. Interior images continue the train theme and show Duffy's journey from being on a train to getting off at her destination, possibly reflecting her career journey. The lack of color and focus only on text and images of Duffy aims to draw attention solely to her music rather than her image.
