OK, so this Johnny Cash Postage Stamp (46 cents) doesn’t exactly need you to lick it to, uhh, stick it, but why pass up an opportunity to get so close to an American icon? It’s a “forever stamp” so it can be slapped on an envelope at any point in your lifetime, but this baby says collectible all the way. It’s based on a 1963 photograph of the singer as he recorded “Ring of Fire: The Best of Johnny Cash.” Plus come on, who could ever get away with licking Johnny Cash while he was alive?
