The United States Postal Services this past Wednesday released yet another forever stamp. This time it honors a Country Music icon. 

The limited edition Johnny Cash Forever stamp is available now. It resembles a 45 rpm record sleeve, and it features a pic taken during a 1963 photo session for the release of his hits album "Ring of Fire: The Best of Johnny Cash"

Stamps are available only for a limited period of time however, they are good at the price purchase regardless how much the rate goes up on a first class letter.
