On May 27, 2010, in Washington, DC, the Postal Service issued a 44-cent Kate Smith commemorative stamp.
The stamp, designed by Ethel Kessler of Bethesda, Maryland, honors Kate Smith, the celebrated singer and entertainer whose signature song, "God Bless America" (composed by Irving Berlin), has been called America's unofficial national anthem. The stamp art duplicates artwork created for the cover of a CD titled "Kate Smith: The Songbird of the South." The artwork was based on a photograph of Smith taken in the 1960s.
Avery Dennison printed 40 million stamps using the gravure process. The stamps appeared in a pressure-sensitive pane of twenty stamps.
