Like some of the old print masters, Nagel was influenced by the Japanese woodblock print, with figures silhouetted against a neutral background, with strong areas of black and white, and with bold line and unusual angles of view. He handled colors with rare originality and freedom; he forced perspective from flat, two-dimensional images; and he kept simplifying, working to get more across with fewer elements. His simple and precise imagery is also reminiscent of the art-deco style of the 1920s and 1930s- its sharp linear treatment, geometric simplicity, and stylization of form yield images that are formal yet decorative.
