I like Catherine D'Amours' beautiful work for Le Quartanier (above), a publishing house in Montreal. In 2013 she designed a series of ten novellas published on the occasion of the tenth anniversary of the house. Each cover has an illustration and a typographic stamp which refer to the content, all illustrations are limited to three colours and added by a simple sans-serif font.
