The 37-cent American Choreographers commemorative stamps were issued on May 4, 2004, in Newark, New Jersey. Ethel Kessler of Bethesda, Maryland, designed the stamps. The stamps honor four extraordinary choreographers � George Balanchine, Martha Graham, Agnes de Mille, and Alvin Ailey. Each left a profound mark on the language of dance. Each stamp contains a collage that features a photographic portrait of the choreographer. Some of the stamps also show members of the choreographer's company dancing.
