Two major spring sales are headlining the Rago/Wright calendar this month. First on Thursday, May 14, 2026, Pure Edge: American Geometric Abstraction, Selected Works from the Museo de Arte Contemporáneo de Buenos Aires is comprised of a cohesive selection of 19 works from the prestigious institution, which boasts a premier collection of American geometric abstraction. Immediately following is the Post War and Contemporary Art sale, bringing together an impressive range of 20th- and 21st-century art, illuminating some of the most significant and pioneering movements of the periods. “These dual offerings underscore Rago/Wright’s expanding leadership in presenting important postwar painting and sculpture,” says Fine Art Director Meredith Hilferty . “We’re deeply proud to bring works of this caliber to market.” Here, we take a closer look at some of the sales’ top lots.
