Leslie's work has an indisputable signature: the architecture, the wielding of the loaded brush, and the consistently present double vertical bands. Whether it is a large oil on canvas or a miniature collage, his work is immediately identifiable. Leslie has the ability to impart scale much like Willem de Kooning and Franz Kline. His small works have great scale and his large works project an even grander sense of scale. This combined with Leslies color sense creates a body of work that epitomizes the power and dynamic of postwar American abstract painting. (A.
