North Korea celebrates missile tests with series of commemorative stamps

— -- North Korea is celebrating its successful test launch of an intercontinental ballistic missile (ICBM) by issuing a series of commemorative stamps.

Another stamp shows Kim and a military leader pumping their fists in celebration, with the country's flag waving high above planet earth and a missile shooting off beside it. Several stamps feature close-up hero images of the missiles.

North Korea has been agitating tensions with Asia and the U.S. this year by launching 11 ballistic missile tests.

Last month, the isolated regime defied a U.N. ban by testing ICBM's on America's July 4th holiday and again on July 28th.

Yesterday, North Korea said through a state run news agency that it would take "thousands-fold" revenge against the United States in response to the sanctions.

North Korea often commemorates significant events with stamps.

The country also released a series of stamps denouncing the U.S. through violent, anti-imperialist artwork last month, according to Quartz.
