Over the course of more than 50 years, renowned American artist Ellsworth Kelly made approximately 400 postcard collages, some of which served as exploratory musings and others as studies for larger works in other mediums. They range from his first monochrome in 1949 through his last postcard collages of crashing ocean waves, in 2005. Together, these works show an unbounded space of creative freedom and provide an important insight into the way Kelly saw, experienced and translated the world in his art. Many postcards illustrate specific places where he lived or visited, introducing biography and illuminating details that make these pieces unique among his broader artistic production. Ellsworth Kelly: Postcards is the most extensive publication of Kelly’s lifelong practice of collaged postcards.
