Date of release not yet known?

The "Man in Black" will soon be the man on stamps. The U.S. Postal Service announced that a Johnny Cashstamp will be released later this year as part of their "Music Icons" series. Two other performers in the series will be announced later this year. Featuring a black-and-white portrait of Cash snapped by Frank Bez in 1963, the stamp is supposed to resemble a 45-record sleeve. A release date for the stamp has yet to be announced.
