From the Postal Bulletin:
On September 23, 2013, in Los Angeles, California and Atlanta, Georgia, the Postal Service™ will issue a Ray Charles (Forever® priced at 46 cents) First-Class mail® commemorative stamp in one design in a pressure-sensitive adhesive (PSA) pane of 16 stamps (Item 579500). The $7.36 Ray Charles pane of 16 stamps may not be split, and the stamps may not be sold individually.
The stamp will go on sale nationwide September 23, 2013.
The U.S. Postal Service® honors Ray Charles, the extraordinary composer, singer, and pianist, who mixed blues, gospel, country, jazz, and soul music in a unique and highly influential pop music style. The stamp, part of the new Music Icons series, features a photograph of Charles from later in his career. The stamp pane evokes the appearance of a vintage 45 rpm record sleeve. One side of the pane includes the stamps and the image of a sliver of a record seeming to peek out the top of the sleeve. The reverse side includes a larger version of the photograph featured on the stamp art and the logo for the Music Icons series. Art director Ethel Kessler worked on the stamp pane with designer Neal Ashby.
