Valerie Jaudon's "Long Division" at Lexington Avenue and 23rd Street serves as a functional security device and a welcoming entry. The 60-foot-long steel fence is an intricate pattern of crisscrossing arches and vertical lines that was designed by the artist to work as panels that form a unified set of connecting arch patterns. "The idea was to make a fence that functions as combination of wall, door, window, and column that allows you to see the entire station," Jaudon says of her work. Based on the success of Jaudon's ornamental work at 23rd St, the MTA determined that similar artist-designed railings should be incorporated system-wide.

During the course of Valerie Jaudon's distinguished 40-year career, she has been committed to redefining the parameters of abstraction. A member of the original Pattern and Decoration group, she is a representative of important tendencies of the larger Postminimalist movement. Jaudon was the driving force behind the influential 1991 Sidney Janis Gallery exhibition, "Conceptual Abstraction," which was later expanded in 2012 in an exhibition in the Hunter College Times Square Galleries. Jaudon has continued to work toward the development of a grammar of abstraction.
