The stamp featuring a picture of the singer is part of the USPS's "Music Icons" series and was released on the singer's birthday.
"The stamp art features an image of Charles, taken later in his career, by photographer Yves Carrère. The stamp sheet was designed to evoke the appearance of a vintage 45 rpm record sleeve. One side of the sheet includes the stamps and the image of a sliver of a record seeming to peek out the top of the sleeve. A larger version of the photograph featured on the stamp and the logo for the Music Icons series appear on the reverse side," USPS wrote on its website.
Charles was best known for his hits "Georgia On My Mind," "Hit the Road, Jack" and "America the Beautiful." He won 17 Grammy Awards as well as many other honors including the Polar Music Prize, the National Medal of Arts and the Kennedy Center Honors.
The Ray Charles stamp is a Forever stamp, which means that it will always be equal in value to the current First-Class Mail one-ounce rate.
