The United States Postal Service revealed Friday that the 33rd stamp in the Literary Arts series of postage stamps honors Ursula K. Le Guin, who increased critical and popular appreciation of sci-fi and fantasy books. She died in 2018. 

The new collectible stamp features a portrait of Le Guin by artist Donato Giancola that's based on a 2006 photograph. The background shows a scene from her 1969 novel The Left Hand of Darkness. In it, an envoy from Earth named Genly Ai escapes from a prison camp in the snowy planet of Gethen with a disgraced Gethenian politician.

The stamp will officially be released be later this year, with the words "three ounce" on it to indicate its usage value. As with Forever stamps, this one will always be valid for the value printed on it.  

Customers can purchase the new stamps through the USPS Postal Store or at post office locations nationwide.
