Alexander Calder made his name as a sculptor, with the hanging mobiles and large-scale stabiles that still occupy public plazas around the world. But he was also a prolific graphic artist, and the same instinct for bold, floating shapes carried directly into his work on paper. His prints and posters have the quality of his three-dimensional work compressed into two dimensions: simple forms, strong color, and a sense that everything is in motion. The pieces here are period originals from across his career.
