The United States Post Office plans to introduce a limited edition series of stamps commemorating influential design movements. I focused on developing a design system around the De Stijl movement, including 12 stamps, an envelope design, info cards, and brochures. With a strong understanding of De Stijl’s principles—pure geometric abstract style and the use of primary colors and neutrals—I ensured that every aspect of the design reflects this art movement. This series not only honors significant design movements but also provides a fun way for people to learn about art.
