The seal, believed to be made in 1651, was looted in Seoul by the U.S. aggression forces during the Korean War (June 1950-July 1953).

During the war, they robbed the Korean Central History Museum in Pyongyang and other museums in local areas of over 6 700 items of antiques and burnt away piles of historical documents.

They also plundered museums in south Korea.

They took away a golden crown dating back to the period of Silla Dynasty (1st century-935) on display at the museum of the Kyongbok Palace.

They took away a number of old paintings, calligraphic works and historical books in museums in Seoul.

Pubyok Pavilion in Pyongyang, Nam Gate in Kaesong City and other historical relics were all vandalized by them.

The aggression forces made use of the three tombs of Kangso in Nampho City as storehouses and turned the old tombs in Ryonggang County into prisons.

They blew up the Anak tombs in South Hwanghae Province.

In May-June 1951, they dropped napalm and incendiary bombs on the scenic Mt. Kumgang to set ablaze the historical relics in the mountain.

The U.S. forces' looting of cultural relics goes on still now in south Korea.

These facts clearly prove that the U.S. is a wrecker of the Korean nation's cultural heritage.
