The National Palace Museum of Korea opened an exhibition on Tuesday of nine royal and national seals from the Chosun Dynasty and earlier that have been returned by the U.S.
The nine seals, which had been looted by U.S. soldiers from Deoksu Palace during the 1950-53 Korean War, were seized by U.S. customs authorities last year. The national treasures were returned after 60 years during the U.S. President Barack Obama's visit to Seoul in late April.
U.S. customs have seized two more Korean royal seals, but it will likely take some time to wrap up all the legal procedures before they are also brought back.
The exhibition runs through Aug. 3.
