You Hong-june, director of the National Museum of Korea, has offered to resign amid a controversy over the museum's display of a misattributed calligraphic work from his private collection. He came under fire after the piece was wrongly introduced as the work of a Korean independence activist before later being found to have been written by a prominent pro-Japanese collaborator during Japan's 1910-45 colonial rule of Korea. The museum removed the item from its ongoing special exhibition following the controversy.
