This photo, provided by the National Museum of Korea on Feb. 22, 2021, shows the country's oldest Taegeukgi, South Korea's national flag. The museum will make the flag public from Feb. 23-March 8 on the occasion of the 102nd anniversary of the March 1 movement against the Japanese colonial rule. The flag is called Denny's, as King Gojong (1863-1907) of the Joseon Dynasty gave it to U.S. consul Owen Denny, who had served as his foreign affairs adviser, when he returned home in 1890.
