Dutch graphic designer Karel Martens (born 1939) has been an influential figure in the visual culture of the Netherlands for many decades. Alongside his commissioned projects, Martens has maintained a commitment to this personal and iterative way of printing, which shows how creative practice often spans perceived disciplinary boundaries.

For each day of this elegant 2026 calendar, Martens has created a unique abstracted form to serve as a number.

The piece’s reference to the daily practice of art expresses Martens’ own approach as a designer and educator: “Every day is a new day!”
