According to BeyondthePerf.com, a web extension of the USA Philatelic catalog, the stamp is meant to resemble a 45 rpm record sleeve. The black-and-white portrait of Cash featured on the stamp was taken by Frank Bez in 1963, during a photo shoot for "Ring of Fire: The Best of Johnny Cash."
USPS representative Mark Saunders said that Cash is the first of three performing artists announced in the series. The other two will be revealed later this year.
The process for selecting topics for its stamps can be a long one for the USPS.
"We get about 40,000 suggestions for stamp ideas each year but only about 20 topics make the cut," Saunders said. "These suggestions are reviewed by the Postmaster General’s Citizens’ Stamp Advisory whose role is to narrow down that 40,000 to roughly 20 and then provide their recommendations to the Postmaster General for final approval."
A release date for the stamp has not been announced.
