A historic 19th-century drawing of the "Taekeukgi," or the Korean national flag, has been found in Britain.

The Independence Hall of Korea said Thursday the copy of a drawing made by Korean envoy to Japan Bak Yeong-hyo in 1882 was found early this month at the British National Archives. It was included among documents sent to a British diplomat in Japan by a Japanese Foreign Ministry official in November 1882.

The Taegeukgi has a red-and-blue taegeuk, similar to the Chinese symbol for yin and yang, at its center. Surrounding the round taegeuk are four sets of black bars, one in each corner of the flag.

The drawing is 142 centimeters wide and 115 centimeters long. The taegeuk in the center is nearly 82 centimeters in diameter.
